General Electric THFK236F000 Hi-Break Circuit Breaker

GE THFK236F000 Hi-Break 3-pole circuit breaker, 600 V, 125 A. This General Electric device is a three-pole protection component intended for three-phase electrical distribution, designed to interrupt fault currents and protect circuits from overloads in industrial or commercial power systems. The unit carries part numbers THFK236F000 and THFK236125, which refer to the same device in GE catalogs. The 3-pole configuration provides simultaneous isolation across all three phases, helping maintain balance in three-phase circuits, while the 600 V rating defines the maximum system voltage and 125 A defines the current rating before tripping. The Hi-Break designation is part of GE's product naming, identifying this device as part of GE's Hi-Break line of protective devices.
