HDA36040 - 40 Amp Circuit Breaker

HDA36040 - 40 Amp Circuit Breaker

The HDA36040 is a 40 Amp, 3-pole thermal magnetic circuit breaker from the Schneider Electric PowerPacT H family. It’s built for compatible I-Line distribution equipment and is often used when a matching H-frame breaker is needed for your replacement, maintenance, or system expansion. The line side connects through the I-Line mounting system, while the load side uses mechanical lugs that accept copper or aluminum conductors from 14 AWG through 3/0 AWG.
