ABB GJL121 Series Contactor, 48V Control Circuit Voltage, 20A Operational Current - GJL1213901R1106

This contactor is an electromechanical switching device designed to control three-phase circuits in industrial, residential and commercial settings. It facilitates motor reversing and load switching using a 48V control input and supports DC contact voltages, making it suitable for installations requiring compact, rail- or wall-mounted switching equipment.

Features and Benefits:

• Three-pole reversing arrangement supports three-phase load switching
• 20 A operational current handles moderate power distribution
• 4 kW power rating enables motor and equipment control
• Screw terminals provide secure electrical connections
• 48V control circuit allows low-voltage Coil operation
• IEC 60947 approvals ensure conformity with recognised standards

Applications

• Suitable for reversing small to medium three-phase motors
• Ideal for control panels with DIN-rail mounting requirements
• Used for distribution switching in commercial premises
• Can be used in residential automation systems requiring DC switching
• Used with equipment where wall mounting is preferred

What is the contact configuration for auxiliary signalling?

It includes a single normally open auxiliary contact for status feedback.

How is the device mounted within electrical installations?

It fits to a DIN rail or can be secured to a wall for flexible panel layouts.

Which environmental temperatures can it operate within?

It is rated to operate from −20 °C up to a maximum of 55 °C.

How many main poles and what contact arrangement does it have?

It is a three-pole device with four normally open main contacts in its normal state.

What Terminal and mechanical form factor should installers expect?

Expect screw-type terminals and a Compact footprint with a width of 96.2mm and a depth of 46.7 mm.
