QPJ3150 - 150Amp Circuit Breaker

QPJ3150 - 150Amp Circuit Breaker

When you replace a breaker in an existing electrical system, getting the details right matters. The Siemens QPJ3150 150 Amp 3-Pole Circuit Breaker is a Type QPJ plug-in breaker designed for compatible electrical distribution equipment. Rated at 150 amps and 240V AC, with a 10kA interrupting capacity, it provides thermal-magnetic protection against overloads and short circuits. For electricians and maintenance teams working with equipment that specifically calls for a QPJ3150, this breaker lets you maintain the original electrical configuration without changing the installation's intended design.

Key Features and Benefits

• 150-Amp Current Rating: Designed for electrical distribution systems that require a 150A circuit breaker.
• Three-Pole Protection: Provides circuit protection across three poles in equipment designed for this configuration.
• Thermal-Magnetic Trip Mechanism: Responds to overloads and short circuits to help protect connected electrical circuits.
• 10kA Interrupting Rating: Rated to interrupt fault currents up to 10,000 amps at 240V AC.
• Type QPJ Plug-In Connection: Intended for compatible electrical equipment specifically approved for this breaker type.
