Overview
The General Electric TEB122050 is a thermal magnetic molded case circuit breaker designed for industrial and commercial electrical protection. This 2-pole unit operates at 240VAC/250VDC with a 50 Ampere current rating and delivers a 10kA (at 240V) and 5kA (at 250VDC) interrupting capacity. The TEB122050 features bolt-on mounting with load-side lug terminals, making it a direct fit for existing GE panelboards and control systems.
