  • Product description

    LC1K Mini Contactor – 3P, 9A, 4kW, 230VAC coil, 1NO auxiliary contact

    A compact three-pole electromagnetic contactor designed for the control of electric motors, lighting, heating, and other three-phase loads. The contactor features 3 main poles, a 9A rated current, is suitable for controlling motors up to 4kW, and includes a 230VAC control coil and 1NO (Normally Open) auxiliary contact.

    Key concept:
    This is a small-sized, reliable, and practical contactor designed for the automatic switching of three-phase loads. It is particularly suitable for electrical panels, motor control circuits, pumps, fans, compressors, lighting groups, and other automation equipment.

    Operating principle

    The contactor operates on an electromagnetic principle. When voltage is applied to the 230VAC control coil, the contactor's electromagnet attracts the contact system and closes the three main power contacts. This turns on the connected load—such as an electric motor, fan, pump, heating element, or lighting circuit.

    When the control coil voltage is disconnected, the contactor returns to its initial position and the main contacts open. The additional 1NO contact can be used for signaling, self-holding circuits, control logic, or for transmitting the contactor's status to another automation system.

    What is the benefit of the 1NO auxiliary contact?
    The normally open auxiliary contact closes together with the contactor's main contacts. It is often used in self-holding circuits for the contactor, for operation signals, indicator lights, or for transmitting a control signal to a relay, PLC, or other automation device.

    Where is it used?

    • Motor control circuits – for smaller three-phase motors up to 4kW.
    • Pump control – for water, circulation, drainage, or technological pumps.
    • Ventilation systems – for fans, air supply, and extraction units.
    • Compressor and mechanism control – where automatic switching via signal is required.
    • Lighting and heating circuits – for group control of larger loads.
    • Automation cabinets – as a power switching element in control systems.

    Practical installation example

    For example, the contactor can be mounted in an electrical cabinet to control a three-phase fan or pump. The three main poles are connected between the circuit breaker and the motor protection or load, while the 230VAC coil is controlled by a button, thermostat, pressure switch, timer, float switch, or PLC output.

    The auxiliary 1NO contact can be used for a self-holding circuit: after pressing the start button, the contactor energizes, and its auxiliary contact maintains power to the coil until the stop contact or protection device is triggered.

    Use case by profession

    Electrician: A compact contactor, convenient to install in control panels and electrical cabinets when managing a three-phase motor up to 4kW or other 9A load.

    Automation specialist: A suitable solution for automating motors, ventilation, pumps, heating, or lighting when the control signal is 230VAC.

    Engineer / Designer: Can be specified for small to medium power three-phase load control systems where 3 main contacts and one normally open auxiliary contact are required.

    Facility or production management: Suitable for the automatic control of technological equipment, smaller motors, fans, pumps, and other electrical loads.

    Pros

    • Compact size – convenient for electrical cabinets with limited space.
    • 3 main poles – suitable for switching three-phase loads.
    • 9A rated current – a practical solution for smaller motors and loads.
    • Up to 4kW motor power – fits many smaller industrial and facility mechanisms.
    • 230VAC coil – convenient for use in standard 230V control circuits.
    • 1NO auxiliary contact – suitable for signaling, self-holding, and automation functions.
    • Low weight – only 0.179 kg.

    Cons / Limitations

    • Limited to 9A loads – for higher current devices, a more powerful contactor is needed.
    • 230VAC control coil – not suitable for direct 24VDC, 24VAC, or other voltage control without additional solutions.
    • Only 1NO auxiliary contact – for complex control schemes, additional contact blocks might be required.
    • No motor protection – it is recommended to use the contactor together with a properly selected motor protection, circuit breaker, or thermal relay.
    • Final selection depends on load type – it is necessary to evaluate the motor's starting current, duty cycle, and specific utilization category.

    Safety and installation notes

    The contactor is an electrical control device; therefore, its selection, connection, and installation must be performed by a qualified electrician or automation specialist.

    • Disconnect power before installation and verify that there is no voltage in the circuit.
    • Check the coil voltage – this model requires 230VAC control voltage.
    • Do not exceed 9A rated current and evaluate the actual load and starting current.
    • Use appropriate protection for motors – such as a motor protection circuit breaker, thermal relay, or other protection solution selected according to the project.
    • Select conductor cross-section and protection devices according to the load, installation method, and applicable regulations.
    • Before ordering, check if the 1NO auxiliary contact is sufficient for the specific control scheme.

    Quick selection guide

    The LC1K0910P7 mini contactor is a suitable choice when a compact 3-pole contactor is needed to control smaller three-phase loads and the control circuit uses 230VAC. It can be used for up to 4kW motors, pumps, fans, compressors, and other automated loads.

    Suitable when you need:
    • A 3-pole contactor for a three-phase load;
    • A contactor for up to 9A rated current;
    • A motor control solution up to 4kW;
    • A 230VAC control coil;
    • A 1NO contact for self-holding or signaling circuits;
    • A compact contactor for an electrical panel.
    Check before installation:
    • Is the coil voltage definitely 230VAC?
    • Does the load current exceed 9A?
    • Do the motor power and starting conditions meet the contactor's specifications?
    • Is an additional NC contact or more auxiliary contacts required?
    • Are proper motor and short-circuit protections installed?
    Important reminder:
    The contactor is not a protection device. It is intended for switching loads on and off; therefore, properly selected protection devices must be used in motor and other load circuits.

    FAQ – Frequently Asked Questions

    Is this contactor suitable for a three-phase motor?
    Yes. The contactor has 3 main poles, so it can be used for controlling three-phase motors and other three-phase loads. Note that the recommended motor power is up to 4kW.
    What does a 230VAC coil mean?
    It means that 230V AC voltage is required to energize the contactor's control coil. The control voltage is typically supplied via a button, relay, thermostat, pressure switch, or automation controller.
    What does 1NO mean?
    1NO means one normally open auxiliary contact. It closes when the contactor is energized and can be used for self-holding, signaling, or automation schemes.
    Can the contactor be used without motor protection?
    It is not recommended. The contactor itself does not protect the motor against overload or short circuits; therefore, proper protection must be used in the motor circuit.
    Is the contactor suitable for lighting or heating loads?
    Yes, it can also be used to control other loads, but it is necessary to verify the actual current, load type, and inrush currents.
    Can this contactor be controlled with 24V voltage?
    Not directly. This model's coil is 230VAC, so for 24V control, you would need to choose a contactor with a 24VDC or 24VAC coil, or use an additional interface relay according to the control scheme.

    Compact contactor for reliable three-phase load control

    The mini contactor is a practical choice for electrical cabinets and control circuits where you need to switch up to 9A three-phase loads or up to 4kW motors.

    3 main poles, a 230VAC control coil, and a 1NO auxiliary contact allow for easy adaptation of the contactor to control pumps, fans, compressors, motors, lighting, or other automated systems.
