HDA36070 - 70 Amp Circuit Breaker

HDA36070 - 70 Amp Circuit Breaker

The HDA36070 is a 70 Amp, 3-pole circuit breaker built for Schneider Electric PowerPacT H I-Line distribution systems. It's most often selected as a direct replacement when an existing H-frame breaker needs to be swapped without changing the panel layout or electrical design. Matching the original breaker helps keep your maintenance straightforward and avoids unnecessary modifications to compatible I-Line equipment.

Rated 25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC, the HDA36070 is intended for commercial and industrial distribution systems where maintaining the original breaker style and electrical ratings is important. In many cases, replacing the breaker simply means confirming the catalog number, amperage, pole configuration, and interrupting rating before installing the new unit.
