UQFB-150 - 150Amp Circuit Breaker

UQFB-150 - 150Amp Circuit Breaker

The UQFB-150 is a 150 amp circuit breaker designed for dependable overcurrent protection in 240-volt electrical systems. It carries a 10,000 amp interrupting rating, which makes it suitable for handling high fault currents without compromising safety. The thermal magnetic trip reacts when it should—during overloads or short circuits—helping protect wiring and connected equipment. Its bolt-on mounting style provides a secure connection that stays stable over time, especially in fixed installations where reliability matters more than anything else.

Key Features and Benefits

• 10,000 Amp Interrupt Rating: Designed to safely interrupt high fault currents when problems occur.
• Bolt-On Mounting: Helps keep the breaker firmly in place and reduces movement after installation.
• Thermal Magnetic Trip: Responds to both long-term overloads and sudden short circuits.
• Non-Metallic Housing: Lightweight and durable for everyday electrical use.
