General Electric TJK436F000 Molded Case Circuit Breaker

General Electric TJK436F000 Molded Case Circuit Breaker is a three-pole protective device from GE used to interrupt current in electrical distribution systems. This unit is rated for 600 volts and 300 amperes, and it features a 300 Amp Trip Plug, indicating its overload protection threshold. As a molded case breaker, the TJK436F000 is designed for compact installation in panelboards or switchgear, offering robust insulation and a durable enclosure for high-current service in demanding environments. The three-pole configuration supports protection of three conductors in typical three‑phase circuits, enabling coordinated interruption of all phases when an overcurrent or fault condition is detected. The model number TJK436F000 identifies the specific GE component within the broader lineup of molded case breakers, providing a reliable option for overload protection in electrical distribution. This specification set—300 A rating, 600 V rating, 3-pole configuration, and a 300 A trip threshold—defines the core capabilities of the device and helps electrical professionals select the correct breaker for a given panel or feeder that requires three‑phase, high-current protection.
