E41B020L - 20Amp Circuit Breaker Description
E41B020L - 20 Amp Circuit Breaker
The E41B020L molded case circuit breaker is a 1-pole, 20-amp protective device designed for dependable circuit protection in electrical distribution systems operating up to 277VAC. Built on the E41 frame, this breaker is engineered for proper form, fit, and function replacement in compatible panels and switchboards where the original device is required. With an interrupting capacity of 22kA at 277VAC and 25kA at 120VAC, it helps protect branch circuits from overloads and short circuits in commercial and industrial environments. Rated for 40°C operation and HACR applications, the E41B020L is suitable for systems that include heating, air conditioning, and refrigeration equipment. The breaker includes line- and load-side terminals, allowing straightforward installation within compatible electrical assemblies. Molded case circuit breakers in this class are known for durable construction and are designed to provide long service life in properly maintained electrical systems.
