Square D QBP22100TM - 100 A, 2-Pole Bolt-On Circuit Breaker | AmpState

Square D QBP22100TM is a 100A, 2-pole bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and loadcenters. Its secure bolt-on design delivers a rigid, vibration-resistant bus connection, helping maintain consistent electrical contact even in challenging environments.

• Secure bolt-on mounting: a robust connection that resists movement and contact wear, reducing the risk of nuisance trips and loose connections over time.
• Thermal-magnetic trip unit: combines a stable thermal element with a responsive magnetic mechanism to deliver repeatable protection for both overloads and short circuits.
• OEM compatibility: designed to integrate with matching Square D loadcenters and panelboards, ensuring proper fit, safe operation, and streamlined maintenance.
• Versatile applications: suitable for residential service panels, light commercial distribution, and small industrial setups where reliable 2-pole protection is required.

Why this breaker matters for your electrical system

When protection matters, the QBP22100TM delivers clarity and reliability. The combination of bolt-on mounting and a thermal-magnetic trip unit means you get a resilient connection and precise response to electrical faults. This translates to fewer unexpected trips, quicker fault isolation, and smoother panel performance in daily operations—from home upgrades to light-duty commercial installations.

Ideal use cases
