QBL22125 - 125 Amp Circuit Breaker

QBL22125 - 125 Amp Circuit Breaker

When you need a 125-amp, 2-pole circuit breaker for a 120/240VAC electrical system, the QBL22125 offers straightforward, reliable circuit protection. It combines thermal and magnetic trip protection to respond to both sustained overloads and short-circuit conditions, helping protect connected equipment from electrical faults. This breaker features a non-interchangeable trip unit, so the trip rating remains fixed rather than being changed in the field. Lug terminals are provided on both the line and load sides, making conductor termination simple during installation or replacement. Whether you're replacing an existing Type QBL breaker or maintaining an electrical distribution system, the QBL22125 is built for applications that require a 125-amp, two-pole breaker with a 10kA interrupting rating at 120/240VAC.
