General Electric THQB320 Bolt-On Circuit Breaker

The General Electric THQB320 bolt-on circuit breaker is a 3-pole, 20-amp, 240-volt protective device from GE’s THQB family, designed for bolt-on mounting. This Type THQB breaker provides overcurrent protection for three-phase circuits by interrupting current when it exceeds its 20 A rating, helping prevent overloads and electrical faults. With a 240 V operating voltage and three-pole configuration, it is intended for multi-phase electrical distributions where balanced protection is required across all conductors. The THQB320 designation identifies the specific member of GE’s bolt-on THQB line, ensuring the device meets the electrical characteristics associated with THQB-type breakers. Use it for safeguarding feeders and branch circuits in environments where GE bolt-on breakers are specified for THQB type applications.
