ABB GJL121 Series Contactor, 20A Current Rating, 48V Control Circuit Voltage - GJL1213001R1016

This contactor is a Compact switching device designed for control and protection tasks in commercial electrical installations. It operates within low-voltage control circuits and is intended to handle switching of three-phase loads, providing a Compact solution for motor control and general-purpose switching in automated systems.

Features and Benefits:

• 48V Coil supports low-voltage control circuits for safer operation
• 3-pole switching delivers 3P distribution for three-phase loads
• 20A operational current enables switching of moderate power circuits
• 690V rated contact voltage allows use in higher-voltage systems
• 4kW power rating suits small motor-control applications
• Screw terminals provide secure, serviceable electrical connections

Applications

• Suitable for controlling small three-phase motors up to 4kW
• Ideal for integration on DIN-rail distribution frames
• Used with wall-mounted panels in light-industrial installations
• Can be used for commercial switching of HVAC and pump systems

What auxiliary contact arrangement is available for control logic?

It includes a single auxiliary contact configured normally closed to support interlocks and signalling.

How does the device mount to control enclosures?

It can be fixed directly to standard DIN rail or attached to a panel wall for flexible installation.

What environmental temperature range can it tolerate during operation?

It is specified to operate reliably between -25°C and 55°C for typical commercial settings.

Which standards govern its safety and performance?

It is manufactured to meet IEC/EN 60947-1, IEC/EN 60947-4-1, IEC/EN 60947-5-1 and corresponding UL equivalents.

How many auxiliary contacts and poles are provided for control and power paths?

The unit provides one auxiliary contact and three power poles for simultaneous three-phase switching.
