Datasheet - GJL1213001R0017

ABB GJL121 Series Contactor, 20A Contact Current, 12V Coil Voltage - GJL1213001R0017

This contactor is a Compact switching device designed to control three-phase loads in commercial, industrial and residential electrical systems. It operates with a 12V control circuit and provides a mains switching solution for motors and power equipment up to 4kW, mounted on DIN rail or fixed to a wall for flexible installation in automated panels and distribution enclosures.

Features and Benefits:

• Three-pole switching delivers three independent line control and safety
• 20A operational current supports medium-duty motor and load switching
• 250V DC and 690V AC ratings allow use with DC and AC supply systems
• Single auxiliary contact offers control-circuit signalling and interlock
• Screw terminals enable secure terminations for repeated service
• Compliance with IEC/EN and UL standards assists regulatory acceptance

Applications

• Suitable for contact control in industrial automation panels
• Ideal for motor switching in light commercial HVAC systems
• Used with residential distribution boards for load management
• Can be used for control of machinery in electronics assembly lines

What environmental temperatures will it tolerate in service?

It is specified to operate between -25°C and 55°C, allowing deployment in typical indoor and sheltered plantroom conditions.

What mounting arrangements are available for panel designers?

It supports both DIN rail attachment and direct wall mounting to suit differing panel layouts and enclosure types.

How many auxiliary contacts are provided for signalling?

There is one auxiliary contact arranged normally as 0NO/1NC to facilitate control logic and status feedback.

What are the physical connection details for electrical contractors?

Terminations use screw-type terminals to secure conductor connections during installation and maintenance.
