E41B030L - 30Amp Circuit Breaker

E41B030L - 30 Amp Circuit Breaker

The E41B030L molded case circuit breaker is a 30-amp, single-pole breaker designed for dependable overcurrent protection in electrical distribution systems that require compatibility with E41 frame configurations. Built for use in 120/277 VAC applications, this breaker helps protect wiring and connected equipment from damage caused by overloads or short circuits. With interrupting ratings of 22kA at 277VAC and 25kA at 120VAC, the E41B030L is well-suited for commercial and industrial panelboard environments where proper fault interruption and stable electrical performance are essential. Designed to operate in environments up to 40°C and HACR rated, it is commonly used in heating, air conditioning, and refrigeration circuits. The breaker includes line-side and load-side terminals for straightforward installation and secure conductor connections. Molded case circuit breakers like the E41B030L are built to last and provide reliable service when used within their specified ratings, making them a practical form-fit functional replacement in compatible legacy electrical systems.
