HED43B070L - 70Amp Circuit Breaker Description
HED43B070L - 70Amp Circuit Breaker
The Siemens HED43B070L is a 70 Amp, 3-pole molded case circuit breaker from the SENTRON ED frame family, built for protecting your 480VAC three-phase electrical distribution systems from overloads and short circuits. It uses a thermal-magnetic trip unit, combining long-time overload protection with instantaneous response to fault conditions. With a 42kAIC interrupting rating at 480VAC, this breaker is intended for installations where the available fault current requires that level of protection.
