Datasheet - GJL1213901R0104

ABB GJL121 Series Contactor, 20A Contact Current, 4kW Power Rating - GJL1213901R0104

This contactor is a three-pole switching device designed to control and reverse electric motors and power circuits in commercial, industrial and residential settings. It operates with a control Coil rated for 110–125V and switches load voltages up to 690V, providing a Compact means to manage motor direction and power delivery where DIN-rail or wall mounting is required.

Features and Benefits:

• 3P configuration provides three-pole switching for three-phase systems
• 20A contact rating supports moderate current loads for motors
• 4kW power rating enables direct motor control within capacity limits
• 110–125V Coil ensures compatibility with common control voltages
• 6A operational current allows use in control circuits with defined Ie

Applications

• Suitable for reversing three-phase motors in production lines
• Ideal for control panels mounted on DIN rails or walls
• Used for switching power in commercial HVAC systems
• Can be used for motor control in light industrial machinery

What Terminal arrangement is provided for wiring?

Screw terminals are supplied to secure power and auxiliary conductors and to facilitate reliable torque connections.

How many auxiliary contacts are available and what is their configuration?

There is one auxiliary contact configured as one normally open contact for signalling or interlock functions.

What environmental temperature range can it operate within?

It functions continuously between -20°C and 55°C, suitable for typical indoor electrical environments.

What mounting options are supported for installation flexibility?

It supports both DIN-rail mounting and direct wall mounting to suit panel and enclosure layouts.

Which standards govern its electrical design?

The device conforms to IEC/EN 60947 series requirements along with equivalent UL standards for similar categories.
