The SQDQOB160 is a high-quality Square D 1P60A 120V Bolt-On Breaker, designed for reliable performance in your electrical system. This single-pole breaker ensures optimal protection against overloads and short circuits, making it an essential component for residential and commercial applications. Upgrade your circuit protection with this durable, efficient breaker today.
The QOB160 uses a bolt-on mounting that physically fastens to the bus bar with a screw, providing a more secure mechanical connection — common in commercial panelboards and certain QO loadcentres designed for bolt-on breakers. The QO160 is the plug-on version that clips onto the bus. They are not interchangeable, so it's important to match the breaker style to your specific panel's bus design.
No — the QOB160 is a single-pole breaker rated at 120V and protects one ungrounded (hot) conductor. For a 240V circuit, you would need a 2-pole QOB breaker of the appropriate amperage. If you're unsure which breaker your application requires, our team can help you select the correct unit.
The Square D QOB series remains an active product line, though specific configurations can sometimes have limited availability through standard supply channels.
