QP20 - 20Amp Circuit Breaker

QP20 - 20Amp Circuit Breaker

Replacing a circuit breaker in an existing electrical system depends on getting the details right. The QP20 20 Amp 1-Pole Circuit Breaker is designed for applications that specifically require a Type QP breaker with a 20 Amp rating. Operating at 120V AC, this single-pole thermal-magnetic circuit breaker protects against overloads and short circuits and has a 10kA interrupting rating. Whether you're maintaining an older electrical panel or replacing a matching breaker in equipment already in service, the QP20 offers the electrical characteristics needed for a proper, like-for-like replacement in compatible installations.

Key Features and Benefits

• 20-Amp, Single-Pole Configuration: Provides overcurrent protection for compatible 120V AC circuits requiring a 20A breaker.
• Thermal-magnetic trip mechanism: Responds to sustained overloads and short-circuit conditions.
• 10kA Interrupting Rating: Rated to interrupt fault currents up to 10,000 amps at 120V AC.
• Type QP Design: Intended for electrical equipment specifically approved for this breaker type.
• 0.75-Inch-Wide Body: Helps match the physical footprint of an existing installation.
• Cable-In/Cable-Out Connections: Supports applications that require this connection arrangement.
