QPJ3225 - 225Amp Circuit Breaker

QPJ3225 - 225Amp Circuit Breaker

When you're maintaining an older electrical system, finding the right circuit breaker means looking beyond amperage alone. The QPJ3225 225 Amp 3-Pole Circuit Breaker is a Type QPJ plug-on, common-trip breaker intended for compatible electrical distribution equipment. Rated at 225 amps with a 10kA interrupting capacity at 120V AC, it provides overcurrent protection in applications that specifically require this breaker configuration.

Key Features and Benefits

• 225-Amp Current Rating: Provides overcurrent protection for compatible electrical equipment requiring a 225A breaker.
• Three-Pole Common-Trip Design: Disconnects all three poles together when a trip occurs, supporting applications that require simultaneous pole operation.
• 10kA Interrupting Capacity: Rated to interrupt fault currents up to 10,000 amps at 120V AC.
• Type QPJ Configuration: Designed for electrical distribution equipment specifically approved to accept this breaker type.
• Plug-On Connection: Provides the mounting and connection arrangement required by compatible QPJ installations.
• Six-Space Requirement: Occupies six 1-inch spaces, an important detail when verifying a replacement breaker's fit.
