C240 - 40Amp Circuit Breaker

C240 - 40Amp Circuit Breaker

The C240 is a 40 Amp, 2-pole circuit breaker designed for you to use in compatible Type C electrical panels. It's commonly used on 120/240VAC circuits where both poles need to trip together if an overload or short circuit occurs. That's the role of the common trip design—if a fault is detected on either pole, both disconnect at the same time.

For many replacement jobs, finding the correct breaker isn't simply a matter of matching the amp rating. The breaker type, pole configuration, voltage rating, and panel compatibility all need to match the existing installation. The C240 is a Type C plug-on breaker, making it a common choice for service work, panel maintenance, and repairs involving compatible equipment.

Its HACR rating allows it to be used in approved heating, air conditioning, and refrigeration applications, but you'll also find breakers like the C240 protecting water heaters, air conditioning condensers, compressors, pumps, and other dedicated 240-volt loads. In most electrical systems, the breaker is something nobody thinks about until it needs to do its job. When a fault occurs, it's expected to react immediately. That's why choosing the correct replacement breaker matters.

Where It Works Best

• The C240 is commonly used in residential, commercial, and light industrial electrical systems requiring a 40 Amp, 2-pole breaker. Typical applications include air conditioning equipment, heat pumps, refrigeration systems, electric water heaters, compressors, pumps, workshop machinery, and other 120/240VAC loads requiring common trip protection. It is often selected during electrical maintenance and breaker replacement projects where matching existing Type C equipment is important.
