ABB GJL121 Series Contactor, 20A Operational Current, 4kW Power Rating - GJL1213001R0104

This contactor is a Compact electromechanical switching device designed for commercial control circuits, providing controlled connection and disconnection of three-phase loads. It is intended for use where space efficiency and straightforward mounting are required, offering reliable switching for motors and other equipment within a controlled industrial environment.

Features and Benefits:

• 20A operational current delivers consistent load switching capability
• 690V contact voltage supports high-voltage three-phase systems
• 3P configuration enables independent control of three poles
• 4kW power rating suits moderate motor and equipment drives
• Screw Terminal design ensures secure electrical connections
• Rated to operate between -25°C and +55°C for varied conditions

Applications

• Suitable for motor control in light industrial automation systems
• Ideal for switching commercial heating and ventilation equipment
• Used with control panels mounted on DIN rail or wall brackets
• Can be used for three-phase load management in plant rooms

What Coil voltages can be selected for this device?

The Coil accepts either 110V or 125V control supplies to energise the unit.

How is the unit mounted in control cupboards?

It is compatible with DIN rail mounting and can also be fixed to a wall if required.

What auxiliary contact arrangement is provided for interlocking or signalling?

A single normally open auxiliary contact is available for auxiliary circuits.

Which standards does the device comply with for industrial installation?

It conforms to applicable IEC/EN and UL standards for low-voltage switching devices.

How many poles and what pole configuration does it use?

The device uses three poles in a 3P pole-and-throw arrangement for three-phase switching.
