HFD63B080 - 80Amp Circuit Breaker

HFD63B080 - 80Amp Circuit Breaker

The Siemens HFD63B080 is an 80A, 3-pole molded case circuit breaker from the SENTRON HFD6 family, made for your equipment that uses the FD frame. It’s rated up to 600VAC and uses a thermal-magnetic trip unit for overload and short-circuit protection. The interrupting rating is 25 kAIC at 600V and 65 kAIC at 480V. It also comes with TA1FD350A lugs on load sides, with conductor ranges of 6 AWG to 350 kcmil copper and 4 AWG to 350 kcmil aluminum.
