QDA222251 - 225 Amp Circuit Breaker

QDA222251 - 225 Amp Circuit Breaker

The QDA222251 is a 225 amp, 2-pole molded case circuit breaker built for use in PowerPact Q-Frame I-Line panelboards and switchboards. It carries a 25kA interrupting rating at 240VAC and is designed to provide standard thermal magnetic protection against overloads and short circuits. This breaker is configured as an I-Line, plug-on style unit with an A-B phase arrangement. It is intended for systems already built around Q-Frame breakers, making it a straightforward form, fit, and function replacement where matching the original specifications matters. When maintaining existing electrical distribution equipment, using the correct frame type and mounting style helps ensure proper alignment and connection inside the panel. The molded case construction houses the trip mechanism and current-carrying components in a compact, durable design. These breakers are built to last and are commonly found in commercial and light industrial facilities where dependable circuit protection is required.
