QDA221001 - 100 Amp Circuit Breaker

QDA221001 - 100 Amp Circuit Breaker

The QDA221001 is a 100 amp, 2-pole molded case circuit breaker designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built on the PowerPact™ Q-Frame platform, this breaker features a thermal magnetic trip unit and a 25kA interrupting rating at 240VAC, making it suitable for branch and feeder applications where consistent overcurrent protection is required. Its I-Line, plug-on configuration allows for straightforward installation in compatible panelboards and switchboards. Designed for proper form, fit, and function, the QDA221001 is commonly used as a direct replacement in existing systems where matching frame type, amperage, and interrupting capacity are critical. Constructed to handle demanding electrical environments, this molded case circuit breaker helps protect conductors and equipment from overloads and short circuits. The 2-pole A-B phase configuration supports 240VAC applications, and the Q-Frame design ensures compatibility within designated PowerPact Q-Frame assemblies. Built to last and engineered for consistent operation, the QDA221001 remains a reliable solution for maintaining the integrity of legacy and existing power distribution systems.
