E42B015 - 15Amp Circuit Breaker

E42B015 - 15 Amp Circuit Breaker

The E42B015 molded case circuit breaker is a 15-amp, 2-pole breaker designed for use in electrical distribution systems that require an E42 frame bolt-on breaker. It provides reliable protection against overloads and short circuits while maintaining compatibility with existing equipment designed for this frame type. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, the E42B015 helps maintain circuit protection in commercial and industrial power systems where these ratings are specified.

This breaker mounts directly to the panel bus using a bolt-on connection, creating a secure electrical and mechanical fit within compatible panelboards. Load-side terminals are included, helping simplify wiring during installation or replacement. The unit is HACR rated, making it suitable for circuits supplying heating, air-conditioning, and refrigeration equipment. Built for long service life, the E42B015 is commonly used when maintaining or servicing existing electrical systems that require a breaker matching the E42 frame configuration.
