QBF32150TS - 150 Amp Circuit Breaker

QBF32150TS - 150 Amp Circuit Breaker

Protect your electrical installation with confidence using the QBF32150TS 150 A molded-case circuit breaker. Designed for three-phase systems at 240 VAC, this unit delivers dependable overcurrent protection and switching control. With its three-pole configuration and 150 A rating, it’s ideal for industrial and commercial panels where safety and performance can’t be compromised. The busbar-style connection (with studs on both line and load sides) makes wiring and maintenance quicker and more secure, reducing installation time and potential wiring faults.

Key Features and Benefits

• High Load Capacity & Safety: Built for 150 amps, this breaker handles heavy electrical loads with ease while offering reliable protection via a thermal-magnetic trip mechanism.
• Strong Fault Handling: It can interrupt fault currents up to 10 kA at both 120/208 V and 240 V, helping to limit damage during short-circuit events.
• Durable & Testable: Rated for up to 1,000 cycles under load (5,000 cycles no-load), it withstands daily operations. A built-in push-to-trip button allows easy manual testing.
• Compact & Practical: With dimensions of 6.47″ × 4.5″ × 3.93″, it fits neatly in many breaker panel arrangements without requiring excessive space.
• Easy to Connect: The busbar-style stud connections simplify installation, and reduce the risk of loose terminations or miswiring.
