    LC2K Reversing Mini Contactor – 3P, 9A, 4kW, 230VAC Coil, 1NO Auxiliary Contact

    A reversing mini contactor designed for changing the rotation direction of three-phase electric motors, as well as for control and automation circuits. The device consists of two interconnected contactors that allow for safe switching of motor phases to select forward or reverse rotation. The contactor features 3 poles, a 9A rated current, 4kW power, a 230VAC control coil, and 1 normally open (NO) auxiliary contact.

    Main concept:
    A reversing contactor is used when it is necessary not only to start or stop a three-phase motor but also to change its direction of rotation. It is suitable for conveyors, gates, lifting mechanisms, fans, pumps, machine tools, and other automation systems where bidirectional motor operation is required.

    Operating principle

    The reversing contactor consists of two contactors: one designed for motor operation in one direction, and the other for the opposite direction. By changing the phase sequence, the rotation direction of the three-phase electric motor is reversed.

    Contactors in a reversing system must be controlled so that both are not engaged at the same time. Therefore, reversing contactors use mechanical and/or electrical interlocking, which prevents short circuits between phases and protects the motor control circuit.

    When is a reversing contactor needed?
    It is required when a motor must operate in both directions: for example, to raise and lower a mechanism, open and close gates, change the direction of a conveyor, or control reversing fans or machine tool mechanisms.

    Key functions

    • Motor rotation direction change – allows switching a three-phase motor to run in forward or reverse direction.
    • Three-phase motor control – designed for 3-phase electric motor control circuits.
    • 230VAC control coil – suitable for control schemes using 230V AC voltage.
    • 1NO auxiliary contact – can be used for signaling, holding circuits, PLC input, or other automation functions.
    • Compact format – convenient for smaller control cabinets, automation panels, and equipment control systems.

    Where is it used?

    • Automatic gates and barriers – for controlling opening and closing mechanisms.
    • Conveyors – to change movement direction based on production process needs.
    • Lifting and lowering mechanisms – in hoists, winches, platforms, and other equipment.
    • Machine tools and workshops – for mechanisms requiring reversing operation.
    • Pump and fan control systems – where direction changes are technologically required.
    • Industrial control cabinets – in motor and automation circuits.

    Practical installation example

    For example, a reversing mini contactor can be used in a three-phase motor control cabinet for a small conveyor. One control button starts the motor forward, and another starts it in reverse. The contactor's interlocking system prevents both directions from being engaged simultaneously.

    The additional 1NO contact can be used for a pilot light, a PLC input, or a holding circuit that keeps the contactor engaged after the control button is released.

    Use cases by need

    For the electrician: a compact reversing contactor suitable for installation in control cabinets and device automation schemes. It is important to correctly connect the phase sequence, control coil, interlock circuit, and motor protection.

    For the engineer/designer: a suitable solution when designing lower-power reversing motor control systems. When choosing a contactor, it is essential to evaluate the motor power, operating current, starting conditions, load category, and control voltage.

    For the industry and maintenance specialist: can be used for reversing control of production equipment, gates, conveyors, hoists, fans, and other mechanisms, as well as for repairing existing contactor systems.

    Pros

    • Reversing control – motor direction can be toggled forward and backward.
    • 3-pole construction – designed for three-phase motor control.
    • 9A rated current – suitable for various small motor control circuits.
    • 4kW nominal power – a practical solution for many industrial mechanisms.
    • 1NO auxiliary contact – suitable for signaling and automation functions.
    • Compact size – convenient for use in smaller control cabinets.
    • Lightweight – only 0.378 kg.

    Cons / limitations

    • Designed for reversing control only – for simple motor starting, a single contactor may be sufficient.
    • Requires proper control scheme – it is essential to ensure both directions cannot be engaged simultaneously.
    • Motor protection required – the contactor does not replace a thermal relay, motor protection circuit breaker, or automatic switch.
    • Power depends on operating conditions – before installation, check the specific motor parameters and load type.

    Safety and installation notes

    The reversing contactor must be installed and connected according to the electrical diagram, manufacturer documentation, and applicable electrical safety requirements. An incorrectly connected reversing scheme can cause short circuits, motor damage, or equipment failure.

    • Installation must be performed by a qualified electrician.
    • Before installation work, disconnect the supply voltage and verify that the circuit is de-energized.
    • Must use proper mechanical or electrical interlocking to ensure both contactors are not engaged at the same time.
    • The motor circuit must include appropriate protection against overload and short circuits.
    • Before selecting the contactor, verify the motor's rated current, power, grid voltage, and load category.
    • The control coil should only be connected to 230VAC control voltage.

    Quick selection guide

    A reversing mini contactor is suitable when you need to control a three-phase electric motor reversibly and the control scheme uses a 230VAC coil. This is a practical solution for smaller motors, gate mechanisms, conveyors, lifting equipment, and various automation systems.

    Suitable when you need to:
    • change the rotation direction of a three-phase motor;
    • control a motor in both forward and reverse directions;
    • use 230VAC control voltage;
    • control circuits up to 9A rated current;
    • use an additional 1NO contact for signaling or automation.
    Check before ordering:
    • whether the motor's rated current and power match the contactor's parameters;
    • whether a 230VAC coil is specifically required;
    • whether a 1NO auxiliary contact is needed;
    • whether motor protection is provided in the control cabinet;
    • whether additional control buttons, relays, or signal lights are required for the reversing scheme.
    Important reminder:
    The reversing contactor must be connected according to the correct reversing motor control scheme. Incorrect phase connection or faulty interlock circuitry can damage the contactor, motor, or the entire control system.

    FAQ – Frequently asked questions

    What is a reversing contactor?
    It is a contactor or a combination of contactors intended for changing the rotation direction of a three-phase electric motor. It allows the motor to operate in both forward and reverse directions.
    What does 3P mean?
    3P means the contactor has three main poles and is intended for controlling three-phase electrical circuits and three-phase motors.
    What does 1NO mean?
    1NO means one normally open auxiliary contact. It can be used for signaling, holding circuits, indication, or input for automation equipment.
    Is this contactor suitable for simple motor starting?
    Yes, but if there is no need to change the motor's rotation direction, it is usually more economical and simpler to use a single standard contactor with appropriate motor protection.
    Does the contactor protect the motor from overload?
    No. The contactor is intended for starting, stopping, and reversing motor control. For overload protection, a suitable thermal relay, motor protection circuit breaker, or other protective equipment must be used.
