E42B015L - 15Amp Circuit Breaker

E42B015L - 15 Amp Circuit Breaker

The E42B015L molded case circuit breaker is designed to provide dependable circuit protection for electrical distribution systems that require a 15-amp, 2-pole breaker within the E42 frame series. Built for use in compatible panelboards and switchboards, this breaker helps protect conductors and connected equipment from overloads and short circuits. With an interrupting capacity of 18kA at 480VAC and 25kA at 240VAC, the E42B015L supports reliable operation in commercial and industrial environments where consistent electrical protection is required. Rated for 40°C operation and HACR applications, this breaker is suitable for systems connected to heating, air conditioning, and refrigeration equipment. The unit includes line-side and load-side terminals, helping ensure proper installation in existing systems where exact form, fit, and function matter. Like many molded case breakers used in legacy power distribution setups, the E42B015L is built with durable internal components intended for long service life when installed and maintained properly.
