E42B100L - 100Amp Circuit Breaker

E42B100L - 100 Amp Circuit Breaker

The E42B100L molded case circuit breaker is designed to provide dependable circuit protection for electrical distribution systems operating at up to 480VAC. Built on the E42 frame, this 2-pole, 100-amp breaker helps safeguard equipment and wiring by interrupting overloads and short circuits within its rated capacity. With an interrupting rating of 18kA at 480VAC and 25kA at 240VAC, it is suited for a wide range of commercial and industrial power distribution panels that require reliable branch circuit protection. The breaker is HACR rated, making it appropriate for heating, air-conditioning, and refrigeration equipment circuits. Its molded case design supports long service life in demanding environments, and line-side and load-side terminals are included, simplifying installation and replacement in compatible systems. For facilities maintaining or servicing existing electrical infrastructure, the E42B100L provides the correct form, fit, and function needed to keep legacy equipment operating as intended.
