ABB GJL121 Series Contactor, 20A Contact Current, 48V AC Coil Voltage - GJL1213501R1006


This contactor is a Compact switching device designed for commercial electrical control systems, providing controlled switching of power circuits in automation and industrial settings. It operates with a 48V AC control circuit and is intended for installations where a small footprint and flexible mounting are required, such as DIN-rail or wall-mounted panels.

Features and Benefits:


• Four poles with 20A operational current for multi-phase switching
• Rated for up to 690V enabling high-voltage circuit use
• 4kW power handling for moderate motor and load control
• Screw Terminal connections for secure wiring termination
• Built to IEC/EN and UL contactor standards for industrial compatibility
• Ambient operation from -20°C to 55°C for varied site conditions

Applications


• Suitable for switching small three-phase motors in commercial settings
• Ideal for control panels requiring DIN-rail mounted components
• Used for replacing Compact contactors in service and maintenance tasks
• Can be used for auxiliary load switching in building management systems

What mounting options are available for installation flexibility?


It can be fitted to standard DIN rails or fixed directly to a wall-mounted panel to suit panel layouts and retrofits.

How is the control circuit powered and interfaced?


The Coil accepts 48V AC control voltage, compatible with typical commercial control supplies and PLC outputs.

What Terminal type is provided for conductor connections?


Terminals use screw-type fastenings to ensure firm conductor clamping and straightforward onsite wiring.

How many poles and what contact configuration does it provide?


The device includes four switching poles and a normal-state arrangement comprising two normally open and two normally closed contacts.

What environmental limits should be observed during operation?


The unit is rated for continuous operation within a temperature range from -20°C up to 55°C, so installations should remain within these bounds.
