C245 - 45Amp Circuit Breaker

C245 - 45Amp Circuit Breaker

The C245 is a 45 Amp, 2-pole circuit breaker designed for you to use in compatible Type C electrical panels. It's commonly installed on 120/240VAC circuits where both poles need to disconnect together if an overload or short circuit occurs. That's the purpose of the common trip design—when the breaker detects a fault, both poles open at the same time to help protect the circuit and connected equipment.

For many replacement projects, the goal isn't simply finding a 45 Amp breaker. The breaker type, pole configuration, voltage rating, and panel compatibility all need to match what's already installed. The C245 is a Type C plug-on breaker, making it a common choice for your electrical maintenance, panel repairs, and equipment replacement where maintaining compatibility is important.

Its HACR rating allows it to be used in approved heating, air conditioning, and refrigeration applications, but breakers like the C245 are also found protecting your water heaters, compressors, pumps, condensers, and other dedicated 240-volt loads. In most electrical systems, a breaker may sit untouched for years. When a fault occurs, though, it's expected to react immediately. That's why selecting the correct replacement breaker matters.

Where It Works Best

• The C245 is commonly used in residential, commercial, and light industrial electrical systems requiring a 45 Amp, 2-pole breaker. Typical applications include air conditioning equipment, heat pumps, refrigeration systems, electric water heaters, compressors, pumps, workshop equipment, and other 120/240VAC loads requiring common trip protection. It is often selected during panel maintenance, electrical repairs, and replacement projects where matching existing Type C equipment is important.
