The GE THQB2120 bolt-on circuit breaker is a 20-amp, two-pole, single-phase device rated for 120/240V. This THQB-series breaker uses bolt-on mounting for direct installation in compatible panels and is designed to provide overcurrent protection for two-pole, split‑phase circuits. With a 20A rating and 120/240V operation, it safeguards both hot legs against overloads in standard electrical distributions.
