  • Product description

    LC1K Contactor | 3P | 6A | 48VAC Coil | 1NO Auxiliary Contact 

    A compact three-pole electromagnetic contactor designed for controlling electrical circuits, small motors, lighting, heating, and other loads. The contactor features 3 main poles, a 6A rated current, a 48VAC control coil, and 1NO normally open auxiliary contact used in control or signaling circuits.

    Main concept:
    This contactor is designed to automatically switch three-phase loads on and off via an external 48VAC control voltage. It is a practical solution for control cabinets, automation systems, low-power motors, lighting, or other electrical circuits that require reliable electromechanical switching.

    Operating principle

    A 48VAC voltage is applied to the contactor's control coil. The coil creates a magnetic field that pulls in the contactor mechanism and closes the three main power contacts. This allows the connected load to receive power.

    When the control voltage is removed from the coil, the contactor's contacts return to their original position, and the load is disconnected. The integrated 1NO auxiliary contact can be used to transmit the contactor's status to a signal light, controller, relay, PLC input, or in self-holding control circuits.

    When is such a contactor useful?
    The contactor is particularly suitable when the main load needs to be controlled by a low control current, and a 48VAC voltage is used in the control circuit. This allows for convenient control of electrical equipment from push-button stations, relays, automation controllers, or other signaling devices.

    Where is it used?

    • In control cabinets – for switching loads on/off and automatic control.
    • In electric motor control circuits – for low-power motors, fans, pumps, or mechanisms.
    • In lighting systems – for group control of luminaires, floodlights, or other lighting loads.
    • In heating and ventilation systems – for controlling electric heating elements, fans, or other devices.
    • In automation projects – when using buttons, timers, relays, PLC controllers, or 48VAC control circuits.
    • In industrial equipment – for signaling, control, and auxiliary electrical circuits.

    Practical installation example

    For example, the contactor can be used in a control cabinet to switch on a three-phase fan or a small pump. The main load circuit is connected through the three power poles of the contactor, while the control button, relay, or automation controller applies 48VAC voltage to the contactor's coil.

    The 1NO auxiliary contact can be used for status indication: when the contactor is energized, it can activate a signal light, transmit a signal to a PLC input, or be used in a self-holding control circuit.

    Usage based on needs

    For an electrician: A compact contactor designed for mounting in control cabinets and connecting three-phase circuits where a 48VAC coil is used for control. The auxiliary 1NO contact helps conveniently implement signaling or self-holding functions.

    For an automation engineer: A suitable solution for systems where the load is controlled via PLC, timer, relay, signaling button, or another 48VAC control device. The auxiliary contact can be used for status feedback.

    For industrial and farm facilities: Can be used to control low-power motors, fans, pumps, lighting groups, and other electrical loads when specific load parameters match the contactor's permissible operating conditions.

    Pros

    • 3 main poles – designed to control three-phase electrical circuits.
    • 6A rated current – suitable for smaller loads.
    • 48VAC control coil – adapted for systems with 48V AC control.
    • 1NO auxiliary contact – useful for signaling, self-holding, or status feedback circuits.
    • Compact size – convenient for installation in control cabinets with limited space.
    • Electromechanical operation – a clear and practical solution for various control circuits.
    • Lightweight – only 0.178 kg.

    Cons / Limitations

    • Coil for 48VAC only – not suitable for direct 230VAC or 24VDC control without additional solutions.
    • 6A rated current – not suitable for high-power loads requiring a larger contactor.
    • Electromechanical device – an operating sound might be heard during switching.
    • Requires proper protection – the contactor itself does not replace a circuit breaker, fuse, or motor protection device.
    • Must be selected according to specific motor load – inrush currents, duty cycle, and usage category must be considered.

    Safety and installation notes

    The contactor is intended for controlling electrical circuits, so it is essential to evaluate the nature of the load, control coil voltage, protection devices, conductor cross-section, and the operating principle of the entire circuit during installation.

    • Installation must be performed by a qualified electrician.
    • Before performing installation work, turn off the power supply and check that there is no voltage in the circuit.
    • Only 48VAC voltage may be supplied to the control coil, unless otherwise specified in the manufacturer's documentation for a specific variant.
    • Do not exceed the 6A rated current and always evaluate the real load and its inrush currents.
    • In a motor circuit, proper motor protection, a thermal relay, or another protection solution selected according to the project design must be used.
    • The 1NO auxiliary contact must be used only for its intended control or signaling functions.
    • Before ordering a replacement contactor, verify the number of poles, coil voltage, auxiliary contact configuration, and load parameters.

    Quick selection guide

    This is a suitable choice when you need a compact 3-pole contactor to control a low-power three-phase load, and a 48VAC coil voltage is used in the control circuit. The integrated 1NO contact provides additional possibilities for signaling or self-holding.

    Suitable when you need:
    • a 3-pole contactor for a three-phase circuit;
    • a 6A rated current contactor for smaller loads;
    • a 48VAC control coil;
    • an additional 1NO contact for signaling or self-holding;
    • a compact solution for a control cabinet.
    Check before ordering:
    • is the control coil voltage exactly 48VAC;
    • do you definitely need 3 main poles;
    • does the 6A rated current fit your specific load;
    • is a 1NO, 1NC, or another combination of auxiliary contacts required;
    • is additional protection required for the load – circuit breaker, fuse, or motor protection device.
    Important reminder:
    The contactor must not be selected based solely on rated current. For motors and other inductive loads, it is essential to evaluate their inrush current, duty cycle, control voltage, and the requirements of the specific electrical circuit.

    FAQ – Frequently asked questions

    What does 3P mean on a contactor?
    3P means the contactor has three main power poles. This design is most commonly used to control three-phase electrical circuits and loads.
    What does a 48VAC coil mean?
    This means the contactor's control coil is designed for a 48V AC voltage. It cannot be directly connected to 230VAC or 24VDC unless a suitable additional solution is used.
    What does a 1NO auxiliary contact mean?
    1NO means one normally open auxiliary contact. It closes together with the contactor activation and can be used for a signal light, PLC input, self-holding circuit, or another control function.
    Can this contactor control an electric motor?
    Yes, it can be used to control a low-power motor, but before selection, it is essential to evaluate the motor's rated and inrush current, operating mode, and the need for additional motor protection.
    Does the contactor provide overload protection?
    No. The contactor is intended for switching a circuit on and off. Protection against short circuits, overloads, or motor overheating requires the use of separately selected protection devices.
    Can a contactor be used instead of a circuit breaker?
    No. A contactor is not a protective device. It is intended for automatic switching, while protection must be ensured by appropriately selected circuit breakers, fuses, or motor protection devices.
