HGA36045 - 45 Amp Circuit Breaker

HGA36045 - 45 Amp Circuit Breaker

The HGA36045 is a 45 amp, 3-pole circuit breaker made for systems that use an HGA frame and I-Line connection. If you’re swapping out an existing unit, this is built to match up without having to rework the panel. It uses a thermal magnetic trip, so it handles both overloads and short circuits the way you’d expect. Nothing complicated—just standard protection for three-phase power setups. The plug-in style lets it seat directly into the bus, which helps speed things up during installs or service work. The size is consistent with other breakers in this frame, so it fits where it’s supposed to without forcing anything. This is the kind of breaker you use when you need the right fit and rating, and you don’t want surprises.
