  • Product description

    LC1K mini contactor 3P 16A – 7.5kW, 24VAC 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, 16A rated current, 7.5kW power, 24VAC control coil, and 1 normally open (NO) auxiliary contact. Due to its compact size, it is convenient for use in control cabinets, smaller automation panels, and equipment control circuits.

    Main idea:
    This mini contactor is designed for switching three-phase electrical circuits on and off when a compact, reliable, and easy-to-install solution is required in a control cabinet. The 24VAC coil allows the contactor to be controlled by standard control voltage, while the 1NO auxiliary contact can be used for signaling, interlocking, or automation circuit logic.

    Operating principle

    The contactor operates on an electromagnetic principle. When voltage is applied to the 24VAC control coil, the coil generates a magnetic field that pulls in the contactor mechanism and closes the main power contacts. This switches on the connected load – for example, an electric motor, fan, pump, or other electrical circuit.

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

    What is the benefit of the LC1K mini contactor?
    The LC1K series mini contactor is a compact solution for when space is limited in a control cabinet but reliable control of a three-phase load is needed. It is suitable for small to medium power motors, automation assemblies, ventilation, lighting, or auxiliary control systems.

    Where is it used?

    • Electric motor control – switching small to medium power three-phase motors on and off.
    • Ventilation systems – control of fans, air supply, or extraction equipment.
    • Pump control circuits – switching on 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 element in circuits controlled by PLCs, relays, or switches.

    Practical installation example

    For example, the contactor is mounted in a control cabinet and used to control a three-phase fan or pump. A control button, relay, timer, pressure switch, or automation controller provides a 24VAC signal to the contactor coil, and the contactor switches on the main power circuit.

    The 1NO auxiliary contact can be used for an indicator light, working status signal, interlocking circuit, or for a controller input so that the system can see when the contactor is energized.

    Usage according to needs

    For an electrician: A convenient contactor for installation in electrical panels, automation boxes, and equipment control circuits. The compact housing allows for space saving in the control cabinet.

    For an engineer/designer: A suitable choice when designing low-power motor, ventilation, heating, lighting, or automation control circuits that require a 3P contactor with a 24VAC control coil.

    For maintenance personnel: Can be used as a replaceable control element in devices requiring a compact three-phase load contactor with an auxiliary contact for signaling or interlocking.

    Pros

    • Compact mini contactor size – convenient for installation in limited space.
    • 3P power contacts – suitable for controlling three-phase circuits.
    • 16A rated current – suitable for many small-power control tasks.
    • 7.5kW power – practical solution for electric motor control.
    • 1NO auxiliary contact – can be used for signaling, indication, or interlocking.
    • Low weight (0.179 kg) – convenient for assembly and installation in panels.
    • Suitable for automation systems – can be controlled via buttons, relay contacts, or controllers.

    Cons / limitations

    • Not suitable for large loads – essential not to exceed 16A and 7.5kW parameters.
    • Does not protect the motor itself – additional protection, such as a motor circuit breaker or thermal overload relay, is required to protect the motor.
    • Requires a proper circuit design – essential to evaluate load type, inrush currents, control voltage, and protection.
    • Must be installed in an electrical panel or a suitable protective enclosure depending on environmental conditions.

    Safety and installation notes

    The contactor is an electrical control device; therefore, before installation, it is essential to evaluate 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 requirements.
    • Before installation, disconnect power and ensure the circuit is de-energized.
    • Do not exceed rated current and power – the load must match the contactor specifications.
    • Control coil voltage must be 24VAC – improper coil voltage can damage the contactor.
    • Motor overload and short-circuit protection is recommended.
    • The contactor must be installed in a suitable electrical panel or enclosure matching the environmental conditions.
