ABB GJL121 Series Contactor, 20A Operational Current, 12V Control Circuit Voltage - GJL1213901R0017

This contactor is a three-pole switching device designed to control and reverse electric motors and power circuits across commercial, industrial and residential installations. It operates from a low-voltage control input and is suitable for panel or rail mounting where compact, functional switching is required.

Features and Benefits:

• 12V control Coil provides straightforward Interface for low-voltage systems
• 20A switching capacity supports moderate current motor loads
• 690V AC and 250V DC ratings permit AC and DC circuit switching
• 3P configuration enables reversing control for three-phase motors
• Screw terminals allow secure conductor connection and maintenance
• UL and IEC conformity supports standardised safety and performance

Applications

• Suitable for reversing three-phase motor drives in factories
• Ideal for control panels with DIN rail or wall mounting
• Used with HVAC systems requiring 12V control circuits
• Can be used for commercial lighting and power distribution switching
• Used for residential motorised gate and shutter control systems

What mounting options are available for installation flexibility?

It can be fixed to DIN rail systems or mounted directly to a wall for varied panel arrangements.

How does the auxiliary contact configuration aid control logic?

The auxiliary set includes a single changeover contact arranged as 0NO/1NC to provide a normally closed signal contact for interlocks or status feedback.

What environmental temperatures can it tolerate during operation?

The device is rated to operate down to -20°C and up to 55°C, suitable for most indoor electrical environments.

What are the physical connector and dimensional considerations for panel design?

The unit uses screw-type terminals and occupies a width of 96.2mm with a depth/length of 46.7mm, informing panel spacing and wiring routing.
