General Electric TE122020 Molded Case Circuit Breaker

The General Electric TE122020 is a molded case circuit breaker rated at 20 amperes with a 240-volt capacity across two poles, designed to provide reliable overcurrent protection within low-voltage electrical power distribution systems. Operated to interrupt the circuit during conditions of short circuit or sustained overload currents affecting branch feeder lines, this unit coordinates effectively with protective equipment in panelboard assemblies. Common applications involving commercial lighting loads, transformer feeds, or small motorized equipment requiring dual-pole isolation benefit from the split-phase power input management inherent in this configuration. Installation relies on verifying the serial markings and voltage ratings match the incoming electrical supply to prevent equipment damage or failure during fault events.
