E41B030 - 30Amp Circuit Breaker

E41B030 - 30 Amp Circuit Breaker

The E41B030 molded case circuit breaker is a 30-amp, 1-pole bolt-on breaker designed for dependable circuit protection in electrical distribution systems operating up to 277VAC. Built on the E41 frame, this breaker provides overcurrent protection for branch circuits while maintaining compatibility with panelboards and equipment designed for bolt-on style breakers. With an interrupting capacity of 22kA at 277VAC and 25kA at 120VAC, the E41B030 helps safeguard electrical systems from damage caused by overloads and short circuits. Designed for environments rated up to 40°C, this breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. The bolt-on mounting configuration ensures a secure mechanical and electrical connection to the panelboard bus, and load-side terminals are included to simplify installation. Molded case circuit breakers like the E41B030 are widely used in commercial and industrial electrical systems and are known for their durable construction and long service life.
