EF2B015 - 15A Circuit Breaker

EF2B015 - 15A Circuit Breaker

If you're maintaining or servicing an existing electrical system that uses EF2-frame breakers, the EF2B015 is a straightforward, compatible option. This 2-pole, 15-amp molded case circuit breaker is built for consistent circuit protection across a range of common voltage applications, including up to 600VAC. It’s designed to handle overloads and short circuits without complicating your setup, making it a practical fit when you need a direct replacement that matches your current configuration. With interrupting ratings of 14k A.I.C. at both 600VAC and 480VAC, and 18k A.I.C. at 240VAC, it aligns with typical system requirements found in commercial and industrial environments. The molded case design helps protect internal components from everyday wear, while its 40°C rating supports stable operation under standard conditions. Overall, this breaker does exactly what it’s supposed to do—fit right, function properly, and keep your system protected.
