GFTCB245 - 45 Amp GFCI (5mA) Circuit Breaker

GFTCB245 - 45 Amp GFCI (5mA) Circuit Breaker

If you’re working with a panel that calls for a Type GFTCB breaker, the GFTCB245 is a straightforward, dependable choice. It’s built to do one job well—protect the circuit and help protect people. With 5mA ground fault protection, it’s designed to trip quickly when it senses leakage, which is especially important in areas where electrical safety is critical. This 2-pole, 45-amp breaker fits where it’s supposed to, installs without fuss, and operates as expected in compatible equipment. The size is compact enough to work comfortably داخل the panel, and the 22kA interrupting rating means it can handle fault conditions without hesitation. It’s the kind of component you install and rely on—no extra complexity, just the right fit and function for the system it’s meant for.
