  • Product description

    LP2K Reversing Mini Contactor – 3P, 12A, 5.5kW, 24VAC Coil, 1NO Auxiliary Contact

    Reversing mini contactor designed for changing the rotation direction of three-phase electric motors, as well as for control and automation circuits. The unit consists of two interlocked contactors that allow for the safe switching of motor phases to select forward or reverse operation. The contactor features 3 poles, 12A rated current, 5.5kW power, a 24VAC control coil, and 1 normally open (NO) auxiliary contact.

    Key Concept:
    A reversing contactor is used when you need 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.

    Control Coil

    Operating Principle

    The 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 rotation direction 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 to prevent a short circuit between phases and to protect 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 gates, change the direction of a conveyor, or control a reversing fan or machine tool mechanism.

    Main Features

    • Motor rotation direction change – allows switching a three-phase motor to operate in forward or reverse direction.
    • Three-phase motor control – designed for control circuits of 3-phase electric motors.
    • 24VAC control coil – suitable for control schemes using 24V AC voltage.
    • 1NO auxiliary contact – can be used for signaling, latching circuits, PLC input, or other automation functions.
    • Compact design – 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 – for changing 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 direction switching is technologically necessary.
    • Industrial control cabinets – in motor and automation circuits.

    Practical Installation Example

    For example, a reversing mini contactor can be used in the motor control cabinet for a small conveyor. One control button activates the motor in forward operation, while the other activates it in reverse. The contactor's interlocking system prevents both directions from being activated simultaneously.

    The auxiliary 1NO contact can be used for a control light, a PLC input, or a latching circuit that keeps the contactor energized after the control button is released.

    Usage by Professionals

    For Electricians: 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 Engineers/Designers: A suitable solution for designing small-power reversing motor control systems. When selecting a contactor, it is essential to evaluate motor power, operating current, starting conditions, utilization category, and control voltage.

    For Industrial and Maintenance Specialists: Can be used for the reversing control of production equipment, gates, conveyors, lifts, fans, and other mechanisms, as well as for repairing existing contactor systems.

    Pros

    • Reversing control – motor direction can be switched 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 0.446 kg.

    Cons / Limitations

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

    Safety and Installation Notes

    The reversing contactor must be installed and connected according to the electrical diagram, manufacturer's documentation, and current electrical safety regulations. An incorrectly connected reversing circuit can cause a short circuit, motor damage, or equipment failure.

    • Installation must be performed by a qualified electrician.
    • Before installation work, turn off the power supply and verify that the circuit is de-energized.
    • Use proper mechanical or electrical interlocking to ensure both contactors are not active simultaneously.
    • Appropriate overload and short-circuit protection must be included in the motor circuit.
    • Before selecting a contactor, verify the motor rated current, power, mains voltage, and utilization category.
    • The control coil must be connected only to 24VAC control voltage.

    Quick Selection Guide

    Reversing mini contactor is suitable when you need to control a three-phase motor reversibly and your control scheme uses a 24VAC coil. It 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 the motor in forward and backward directions;
    • Use 24VAC control voltage;
    • Control circuits up to 12A rated current;
    • Use an additional 1NO contact for signaling or automation.
    Check before ordering:
    • Does the motor's rated current and power match the contactor's parameters?
    • Is a 24VAC coil required?
    • Is a 1NO auxiliary contact needed?
    • Is motor protection planned in the control cabinet?
    • Are additional control buttons, relays, or signal lights needed for the reversing circuit?
    Important Reminder:
    The reversing contactor must be wired according to the correct reversing motor control diagram. Incorrectly connected phases or interlocking circuits can 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, allowing the motor to operate in forward and reverse directions.
    What does 3P mean?
    3P means the contactor has three main poles and is intended for controlling three-phase electric circuits and three-phase motors.
    What does 1NO mean?
    1NO means one normally open auxiliary contact. It can be used for signaling, latching circuits, indication, or as an input for automation equipment.
    Is this contactor suitable for simple motor starting?
    Yes, but if reversing the motor's direction is not required, 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 for starting, stopping, and reversing motor operation. For overload protection, a proper thermal relay, motor circuit breaker, or other protective equipment must be used.
