C370 - 70Amp Circuit Breaker

C370 - 70Amp Circuit Breaker

The C370 is a 70 Amp, 3-pole circuit breaker built for protecting three-phase electrical circuits in commercial and industrial environments. With a common-trip design, all three poles disconnect together when a fault occurs, helping prevent damage to connected equipment and reducing the risk of electrical system issues.

Whether you're replacing an existing breaker during maintenance or upgrading equipment in a panel, the C370 offers a straightforward plug-on installation that helps keep projects moving.

You'll commonly find breakers like the C370 protecting motors, HVAC equipment, distribution panels, and other three-phase loads that demand reliable overcurrent protection.
