LP1K Mini Contactor – 3P, 12A, 5.5kW, 24V DC Coil, 1NO Auxiliary Contact

Mini contactor designed for controlling electric motors, pumps, fans, heating, lighting, and other automation circuits. The contactor features a 3-pole main power circuit, is rated for loads up to 12A, includes a 24V DC control coil, and one integrated 1NO (normally open) auxiliary contact. Its compact design allows for convenient mounting in control panels and space-constrained areas.

• Motor Control – for switching small and medium-power motors on and off.
• Pump Control Panels – for controlling water supply, drainage, circulation, and process pumps.
• Ventilation Systems – for controlling fans, air supply, and extraction equipment.
• Heating and Lighting Systems – for switching loads based on thermostat, timer, relay, or controller signals.
• Automation Panels – when using 24V DC PLCs, sensors, or relay outputs for control.
• Equipment Retrofitting – for replacing worn-out or faulty similar-type contactors.

For example, the contactor can be installed in a pump control panel. The main three-phase motor circuit is connected through the contactor’s power terminals, while the 24V DC coil is controlled by a float switch, pressure relay, PLC controller, or another automation device.

The integrated 1NO auxiliary contact can be used for self-holding (to keep the contactor energized after releasing the start button) or to provide a signal to a PLC, an indicator light, or another control circuit function.

For Electricians: A convenient contactor for control panels, motor starter circuits, and switching ventilation, pump, heating, and lighting loads. Its compact size helps save space in the panel.

For Automation Engineers: The 24V DC control coil allows for easy integration with PLC controllers, relay outputs, sensors, timers, and other automation components.

For Industrial and Utility Specialists: Suitable for use in equipment control systems where reliable switching of motors, pumps, fans, or other electrical loads is required.

For Maintenance Specialists: Can be used as a replacement for similar models, after verifying the coil voltage, contact configuration, current rating, mounting method, and load parameters.

The contactor is an electrical control component; it must be selected and installed according to the specific electrical schematic, load type, control voltage, and applicable electrical safety requirements.

• Installation must be performed by a qualified electrician.
• Before installation or maintenance, disconnect the power supply and check that no voltage is present in the circuit.
• The control coil must be powered only by 24V DC voltage.
• Before connecting, check the terminal markings according to the contactor diagram and manufacturer documentation.
• In motor circuits, provide appropriate overload and short-circuit protection.
• Do not exceed the rated 12A current and account for starting, inductive, and other transient currents.
• When replacing an old contactor, ensure the number of poles, coil voltage, auxiliary contact configuration, load capacity, and mounting method match.

Quick Selection Guide

This mini contactor is suitable when you need a compact 3-pole contactor with a 24V DC coil, rated for loads up to 12A and motors up to 5.5kW. It is especially useful in automation panels, pump, ventilation, and motor control circuits.

Compact Contactor for Professional Control Circuits

The mini contactor is a practical solution for controlling motors, pumps, fans, heating, and other electrical loads. Its 3-pole power circuit, 12A rated current, 24V DC coil, and 1NO auxiliary contact make it suitable for various automation and control panels.

Before choosing a contactor, verify the control coil voltage, load current, motor power, auxiliary contact requirements, and planned protection measures to safely adapt the device to your specific electrical circuit.
