HDA36110 - 110 Amp Circuit Breaker

HDA36110 - 110 Amp Circuit Breaker

The HDA36110 is a 110 Amp, 3-pole circuit breaker from Schneider Electric's PowerPacT H family. It's used in compatible I-Line panelboards and switchboards and is commonly purchased to replace your existing H-frame breaker with the same electrical ratings and mounting style.

This model uses a thermal-magnetic trip unit, which combines overload protection with an instantaneous response to short-circuit faults. Because the trip settings are factory calibrated, there's nothing to adjust during installation, making it a straightforward option for your maintenance departments and electrical contractors replacing a failed breaker.
