EF2B030 - 30Amp Circuit Breaker

EF2B030 - 30 Amp Circuit Breaker

When you’re working with an existing electrical system, the last thing you want is guesswork. The EF2B030 molded case circuit breaker is built to match the original form, fit, and function of EF2 frame installations, making it a straightforward solution for keeping your system operating the way it was designed. Whether you're handling routine maintenance or replacing a failed breaker, this 2-pole, 30-amp unit delivers consistent circuit protection across a range of standard commercial and industrial applications.

Designed for use in systems up to 600VAC, the EF2B030 provides reliable interrupting capacity where it counts. Its molded case construction is made to last, standing up to everyday electrical demands without unnecessary complexity. With a 40°C calibration, it aligns with typical enclosure conditions, helping ensure predictable operation under normal working environments. For electricians and maintenance teams, this means less downtime, fewer surprises, and a smoother path to getting systems back online.
