QBA221002 - 100 Amp Circuit Breaker

QBA221002 - 100 Amp Circuit Breaker

The QBA221002 is a 100 amp, 2-pole molded case circuit breaker from the PowerPact™ Q-Frame series, designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Rated at 10kA interrupting capacity at 240VAC, this breaker provides essential protection against overloads and short circuits in 240V applications. Its thermal magnetic trip unit delivers time-delayed protection for overload conditions and instantaneous response for short circuits, helping safeguard conductors and connected equipment. Built for I-Line, plug-on mounting systems, the QBA221002 is engineered for proper form, fit, and function in compatible panelboards and switchboards where QBA frame breakers are specified. With its solid construction and molded case design, this unit is built to last and suited for long-term service in demanding electrical environments.
