QBM22150TN - 150 Amp Circuit Breaker

QBM22150TN - 150 Amp Circuit Breaker

The PowerPacT™ QBM22150TN 2-Pole Circuit Breaker is built to keep your electrical systems safe and running smoothly. Designed for 240VAC applications, it handles up to 150 amps with a breaking capacity of 10kA, giving you dependable protection against overloads and short circuits. This breaker uses a thermal-magnetic trip system for accurate, automatic shutdown when needed, and it even has a manual trip button for extra control. With an 80% continuous current rating, it’s made to manage heavy electrical loads day after day. Installation is straightforward thanks to the included lugs and terminal nuts, and it’s tough enough to last through thousands of on/off cycles without compromising performance.

Key Features and Benefits

• Strong Fault Protection: Handles fault currents up to 10kA at 208Y/120VAC and 240VAC to help prevent equipment damage.
• Reliable Safety: Thermal-magnetic trip system automatically responds to overloads and short circuits for consistent protection.
• Made to Last: Built to endure 1,000 mechanical cycles under load and 5,000 cycles with no load, keeping downtime to a minimum.
• Quick Setup: Load-side lugs and line-side terminal nuts make installation fast and secure.
• Manual Control: Push-to-trip button gives you the option to shut it off manually when needed.
