Overview

The ABB TJK436T300 is a 3-pole, 400-amp thermal-magnetic trip unit designed for ABB J600 line industrial circuit breakers. This interchangeable trip unit (SKU: TJK436T300) provides precise overcurrent protection in electrical distribution systems by combining thermal and magnetic trip mechanisms to safeguard against sustained overloads and short-circuit events. The thermal trip responds to gradual overcurrent conditions, while the magnetic trip provides instantaneous protection during fault conditions, ensuring rapid response to protect downstream equipment. Engineered for compatibility with both Standard and Hi-Break frames within the J600 series, the TJK436T300 offers installation flexibility for new and existing systems. The unit includes copper/aluminum (Cu/Al) line and load lugs for secure conductor connections, supporting both copper and aluminum wiring without additional adapters. This trip unit is manufactured in the USA under ABB Electrification’s quality standards, ensuring reliable performance in industrial environments. Key applications include industrial power distribution panels, motor control centers, and feeder circuits where 400-amp three-phase protection is required. The TJK436T300 is not suitable for reverse feed applications, requiring proper installation orientation to maintain compliance with safety standards. For systems requiring higher interrupting ratings, pair this trip unit with compatible ABB J600 Hi-Break frames to achieve up to 65 kAIC interrupting capacity. This component is classified under UNSPSC code 39121601, identifying it as a critical element in industrial electrical infrastructure. Trust ABB’s proven thermal-magnetic technology for dependable circuit protection in demanding applications.
