HFD63B150 - 150Amp Circuit Breaker

HFD63B150 - 150Amp Circuit Breaker

The Siemens HFD63B150 is a 150A, 3-pole molded case circuit breaker built for compatible SENTRON equipment that uses the FD frame. It is rated for your applications up to 600VAC and uses a thermal-magnetic trip unit for overload and short-circuit protection. The breaker is rated 25 kAIC at 600V and 65 kAIC at 480V, which are important values to confirm against the electrical system before installation.
