  • Product description

    LC1K Mini Contactor 3P 12A – 5.5kW, 230VAC Coil, 1NO Auxiliary Contact

    Mini contactor designed for the control of electric motors, fans, pumps, lighting, heating, and automation circuits. The contactor features 3 poles, 12A rated current, 5.5kW power, a 230VAC control coil, and 1 normally open (NO) auxiliary contact. Due to its compact size, it is ideal for use in control cabinets, small automation panels, and equipment control circuits.

    Key Concept:
    This mini contactor is intended for switching three-phase electrical circuits on and off, providing a compact, reliable, and easy-to-install solution for control panels. The 230VAC coil allows the contactor to be controlled by standard control voltage, while the 1NO auxiliary contact can be used for signaling, interlocking, or control circuit logic.

    Operating Principle

    The contactor operates on the electromagnetic principle. When voltage is applied to the 230VAC control coil, it creates a magnetic field that attracts the contactor's mechanism, closing the main power contacts. This activates the connected load, such as an electric motor, fan, pump, or other electrical circuit.

    When the control voltage is removed from the coil, the mechanism returns to its original position, and the power contacts disconnect. The additional 1NO contact can be used for contactor status indication, interlocking, signal control, or auxiliary logic in the control scheme.

    Why choose the LC1K mini contactor?
    The LC1K series mini contactor is a compact solution for situations where control panel space is limited, but reliable switching of three-phase loads is required. It is suitable for small and medium-power motors, automation nodes, ventilation, lighting, and auxiliary control systems.

    Where is it used?

    • Electric motor control: For starting and stopping small and medium-power three-phase motors.
    • Ventilation systems: For controlling fans, air supply, or extraction units.
    • Pump control circuits: For activating water, circulation, or process pumps.
    • Lighting and heating systems: When the load needs to be controlled via an automation signal.
    • Automation and control cabinets: As a compact actuator in PLC, relay, or switch-controlled circuits.

    Practical Mounting Example

    For example, the contactor is installed in a control cabinet to manage a three-phase fan or pump. A control button, relay, timer, pressure switch, or PLC sends a 230VAC signal to the contactor coil, and the contactor switches on the main power circuit.

    The 1NO auxiliary contact can be used for an indicator lamp, working status signal, interlocking circuit, or PLC input to allow the system to detect when the contactor is energized.

    Application by Need

    Electrician: A convenient contactor for installation in electrical panels, automation boxes, and equipment control circuits. The compact housing saves space in the control cabinet.

    Engineer / Designer: A suitable choice for designing low-power motor, ventilation, heating, lighting, or automation control circuits that require a 3P contactor with a 230VAC coil.

    Maintenance Specialist: Can be used as a replaceable control element in machines requiring a compact three-phase load contactor with an auxiliary contact for signaling or interlocking.

    Pros

    • Compact mini contactor size: Saves space in limited areas.
    • 3P power contacts: Suitable for switching three-phase circuits.
    • 12A rated current: Suitable for many small-power control tasks.
    • 5.5kW power: Practical solution for motor control.
    • 230VAC coil: Common standard control voltage.
    • 1NO auxiliary contact: Can be used for signaling, indication, or interlocking.
    • Lightweight – 0.178 kg: Easy to mount and manage in panels.
    • Automation-friendly: Can be controlled by buttons, relay contacts, or controllers.

    Cons / Limitations

    • Not for heavy loads: Must not exceed 12A and 5.5kW parameters.
    • 230VAC coil: Not suitable for systems using 24VAC, 24VDC, or other control voltages.
    • Does not protect the motor itself: Additional protection like a motor circuit breaker or thermal overload relay is required.
    • Requires correct schematic: Load type, starting currents, control voltage, and protections must be assessed.
    • Installation: Must be performed in an electrical cabinet or appropriate protective enclosure according to environmental conditions.

    Safety and Installation Notes

    The contactor is an electrical control device; therefore, before installation, it is essential to assess load current, control voltage, motor power, protective devices, wire cross-section, and the installation environment.

    • Installation must be performed by a qualified electrician in accordance with electrical safety regulations.
    • Disconnect power before installation and check that the circuit is de-energized.
    • Do not exceed rated current and power: Load must match contactor specifications.
    • Coil voltage must be 230VAC: Incorrect coil voltage can damage the contactor.
    • Motor protection recommended: Overload and short-circuit protection should be included.
    • Mount inside an appropriate electrical panel or housing according to environmental standards.
