HED41B025 - 25Amp Circuit Breaker

HED41B025 - 25Amp Circuit Breaker

The Siemens HED41B025 is a 25 Amp, one-pole thermal magnetic circuit breaker designed for Siemens SENTRON low voltage molded case circuit breaker systems using the ED frame style. This breaker is commonly used when servicing existing electrical equipment and a matching replacement is needed to keep the original breaker specifications in place. With a 277V rating, 65kAIC interrupting capacity, and thermal magnetic trip unit, the HED41B025 provides circuit protection for compatible applications while maintaining the same form, fit, and functional requirements of your existing system.
