EH3B015 - 15Amp Circuit Breaker

EH3B015 - 15 Amp Circuit Breaker

If you're working on an existing electrical system and need a breaker that fits right the first time, the EH3B015 molded case circuit breaker keeps things simple. It’s built for straightforward replacement in EH3 frame setups, so you’re not dealing with modifications, guesswork, or compatibility issues. This 3-pole, 15-amp breaker is commonly used in commercial and industrial environments where maintaining system continuity matters. Once installed, it does exactly what it’s supposed to do—protect your circuits and keep everything operating as designed.

With interrupting ratings of 14kA at 480VAC and 18kA at 240VAC, the EH3B015 is suited for handling fault conditions in systems that rely on consistent, properly matched components. The molded case housing helps shield internal parts from environmental factors, while its construction reflects what these breakers are known for—they’re built to last and stay in service.
