ABB GJL121 Series Contactor, 20A Operational Current, 12V Control Circuit Voltage - GJL1213901R0107

This contactor is a Compact electrically operated switching device designed for reversing motor control in commercial, industrial and residential installations. It provides a three-pole switching arrangement for power circuits and is intended for mounting on a DIN rail or directly to a wall. The unit is suited to control circuits running at low control voltages and integrates a single auxiliary contact for signalling or interlock purposes.

Features and Benefits:

• 12V Coil enables low-voltage control circuit compatibility
• 20A operational current supports moderate motor and load switching
• 690V maximum contact voltage for high-voltage distribution use
• 3P configuration allows three-phase reversing control
• Screw terminals provide secure conductor connections
• Conforms to recognised IEC and UL contactor standards

Applications

• Suitable for reversing small three-phase motors in plant equipment
• Ideal for motor control panels in light industrial settings
• Used for load switching in residential distribution systems
• Can be used in automation racks mounted on DIN rail assemblies
• Suitable for control circuits requiring an auxiliary signal contact

What environmental temperature range can it operate within?

It is rated to function between -20°C and 55°C, permitting use in typical indoor and sheltered outdoor electrical enclosures.

How many auxiliary contacts are available for control signalling?

There is one normally open auxiliary contact provided for status feedback or interlock circuits.

What mounting options exist for secure installation?

The product supports both DIN rail attachment and direct wall mounting to suit panel or enclosure configurations.

What terminals are used for connecting power and control conductors?

Screw-type terminals are provided to accommodate standard wiring practices and ensure reliable clamping.

What power capacity does it manage for motor applications?

It is specified with a power rating of 4 kW, appropriate for small motor and general load switching in three-phase systems.
