EF2B030 - 30Amp Circuit Breaker

EF2B030 - 30Amp Circuit Breaker

When you’re working on existing electrical systems, having the right replacement breaker matters just as much as the repair itself. The EF2B030 is a 30 Amp, 2-pole Type EF2 molded case circuit breaker designed for compatibility with systems that require this specific frame type and footprint. It’s commonly used in maintenance situations where the goal is to keep equipment operating as originally designed, without changing panel layouts or electrical configurations.

This breaker is rated for 30 amps and supports multiple voltage applications, with interrupting ratings of 18 kA at 240 VAC and 14 kA at 480 VAC and 600 VAC. That flexibility makes it suitable for a range of commercial and industrial electrical environments where consistent circuit protection is needed.
