ABB GJL121 Series Contactor, 20A Operational Current, 4kW Power Rating - GJL1213901R0105


This contactor is an electromechanical switching device designed to control three-phase loads in commercial, industrial and residential environments. It provides reversing capability for motor circuits and other applications where remote switching of power is required, operating from a control voltage compatible with standard 220–240V control supplies.

Features and Benefits:


• 3P configuration delivering 20 A operational current for load switching
• Rated for up to 690V AC to handle high-voltage three-phase systems
• 250V DC contact rating for DC switching applications
• Single normally open auxiliary contact to facilitate control interlocking
• Screw terminals that ensure secure, low-resistance conductor connections
• DIN-rail or wall mounting for flexible panel installation

Applications


• Suitable for reversing three-phase motors in HVAC systems
• Ideal for switchgear in light industrial machinery control panels
• Used with building automation for commercial lighting and power control
• Can be used for residential motor-driven systems requiring remote reversal

What control voltages will activate the device?


The control Coil accepts 220V or 240V and is specified to operate across a 220 to 240V control range.

How many switching poles and auxiliary contacts are provided?


It uses a three-pole switching arrangement with one auxiliary contact configured as normally open.

What Terminal and mounting options are available for installation?


Electrical terminations are MADE via screw-type terminals and the unit can be fitted to a DIN rail or mounted on a wall.

What environmental temperature range can it operate within?


The device is rated to function down to −20 °C and up to a maximum ambient of 55 °C.
