  • Product description

    LC2K Reversing Mini Contactor – 3P, 12A, 5.5kW, 230VAC Coil, 1NO Auxiliary Contact

    Reversing mini contactor designed for changing the direction of rotation of three-phase electric motors and for control and automation circuits. The device consists of two interlocked contactors that allow for safe switching of motor phases to select forward or reverse rotation. The contactor features 3 poles, 12A rated current, 5.5kW 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

    A reversing contactor is composed of two contactors: one for operating the motor in one direction and the other for the opposite direction. By changing the phase sequence, the direction of rotation of the three-phase electric motor is reversed.

    Contactors in a reversing system must be controlled so that both are not energized at the same time. Therefore, reversing contactors use mechanical and/or electrical interlocking, which helps prevent phase-to-phase short circuits and protects the motor control circuit.

    When is a reversing contactor required?
    It is required when a motor must work in both directions: for example, to raise and lower a mechanism, open and close a gate, change the direction of a conveyor, or control a reversible fan or machine tool mechanism.

    Main functions

    • Changing motor rotation direction – allows switching a three-phase motor to run forward or reverse.
    • Control of three-phase motors – designed for control circuits of 3-phase electric motors.
    • 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 according to production process requirements.
    • 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 operational requirements demand a change in direction.
    • 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 turns the motor forward, and another turns it in reverse. The contactor interlocking system prevents both directions from being engaged simultaneously.

    The additional 1NO contact can be used for an indicator light, a PLC input, or a holding circuit that keeps the contactor energized after releasing the control button.

    Application by user

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

    For the engineer/designer: a suitable solution for designing small-power reversing motor control systems. When selecting a contactor, it is necessary to evaluate motor power, operating current, starting conditions, utilization 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.
    • 12A rated current – suitable for various small motor control circuits.
    • 5.5kW 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 0.36 kg.

    Cons / limitations

    • Designed for reversing control only – for simple motor starting, a single contactor may be sufficient.
    • Requires a correct control scheme – necessary to ensure both directions cannot be engaged simultaneously.
    • Requires motor protection – a contactor does not replace a thermal overload relay, motor circuit breaker, or MCB.
    • Power depends on operating conditions – check specific motor parameters and load type before mounting.

    Safety and installation notes

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

    • Installation must be performed by a qualified electrician.
    • Before installation, disconnect power supply and verify that the circuit is de-energized.
    • Use appropriate mechanical or electrical interlocking so that both contactors are never engaged at the same time.
    • The motor circuit must include appropriate protection against overload and short circuits.
    • Before selecting a contactor, verify the motor's rated current, power, mains voltage, and utilization category.
    • The control coil must be connected only 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. It is a practical solution for smaller motors, gate mechanisms, conveyors, lifting equipment, and various automation systems.

    Suitable when you need to:
    • change three-phase motor rotation direction;
    • control a motor in both forward and reverse directions;
    • use 230VAC control voltage;
    • control circuits up to 12A rated current;
    • use an additional 1NO contact for signaling or automation.
    Check before ordering:
    • does motor rated current and power match contactor parameters;
    • is 230VAC coil specifically required;
    • is a 1NO auxiliary contact needed;
    • is motor protection included in the control cabinet;
    • are additional control buttons, relays, or indicator lights needed for the reversing scheme.
    Important reminder:
    The reversing contactor must be wired according to the correct motor reversing control diagram. Incorrect phase wiring or interlocking circuit connection may damage the contactor, motor, or the entire control system.

    FAQ – Frequently asked questions

    What is a reversing contactor?
    It is a contactor or contactor assembly designed to change the rotation direction of a three-phase electric motor. It allows the motor to operate in both forward and backward directions.
    What does 3P mean?
    3P means the contactor has three main poles and is intended for controlling three-phase electrical circuits and motors.
    What does 1NO mean?
    1NO means one normally open auxiliary contact. It can be used for signaling, holding circuits, indication, or input to automation equipment.
    Is this contactor suitable for simple motor starting?
    Yes, but if the motor does not need to change direction, it is usually more economical and simpler to use one standard contactor with appropriate motor protection.
    Does the contactor protect the motor from overload?
    No. The contactor is designed for starting, stopping, and reversing control of the motor. For overload protection, an appropriate thermal relay, motor circuit breaker, or other protection equipment must be used.
