QBA221502 - 150 Amp Circuit Breaker

QBA221502 - 150 Amp Circuit Breaker

The QBA221502 is a 150 amp, 2-pole molded case circuit breaker built for use in commercial and industrial distribution systems that require a PowerPact Q-Frame, I-Line configuration. Designed with a thermal magnetic trip unit, it protects circuits from overloads and short circuits by combining time-delayed thermal response with instantaneous magnetic tripping. Rated for 10kA at 240VAC, this breaker is intended for systems where those electrical specifications are required. Its plug-on, I-Line mounting style allows it to install directly into compatible panelboards and switchboards designed for QBA frame breakers. Built to last, the QBA221502 is commonly used as a direct replacement where matching amperage, frame type, and interrupting rating are essential.

Key Features and Benefits

• 150 Amp Rating: Designed to provide overcurrent protection for circuits requiring 150A capacity.
• 2-Pole Design: Suitable for 240VAC applications on A-C phase systems.
• 10kA @ 240VAC Interrupting Rating: Capable of safely interrupting fault currents up to 10,000 amps.
• Thermal Magnetic Trip Mechanism: Protects against sustained overloads and short circuits.
• QBA (PowerPact Q-Frame): Ensures compatibility with equipment designed for this specific frame type.
• I-Line, Plug-On Mounting: Fits properly into designated I-Line panelboards and distribution equipment.
• Molded Case Construction: Fully enclosed housing helps protect internal components during normal operation.
