E42B030L - 30Amp Circuit Breaker

E42B030L - 30 Amp Circuit Breaker

The E42B030L molded case circuit breaker is a 2-pole, 30-amp unit designed to provide dependable circuit protection in electrical distribution systems operating at up to 480VAC. Built on the E42 frame, this breaker is intended for use as a form, fit, and functional replacement in compatible legacy panelboards and switchgear. With an interrupting rating of 18kA at 480VAC and 25kA at 240VAC, it helps protect electrical equipment and conductors by interrupting overloads and short circuits within rated capacities. The breaker is HACR rated and designed for operation in environments up to 40°C, making it suitable for a range of commercial and industrial installations. Line and load-side terminals are included, simplifying installation and ensuring proper connection within compatible systems. Molded case circuit breakers like the E42B030L are built to last and remain a practical solution when maintaining or servicing established electrical infrastructure.
