Square D QO2150VH - 150 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

The Square D QO2150VH is a 150A, 240V, 2-pole plug-in molded case circuit breaker designed for dependable branch circuit protection in panelboards and loadcenters. Built to snap into compatible QO load centers, this unit delivers quick installation and easy replacement when you need it most.

Why this breaker stands out

• Fast plug-in connection enables rapid installation and straightforward replacements, minimizing panel downtime during upgrades or maintenance.
• Thermal-magnetic trip unit provides stable, repeatable protection performance across a range of fault conditions, helping prevent nuisance trips while guarding against insulation damage and short circuits.
• 2-pole, 150A, 240V design ensures coordinated protection for both conductors in a 240V circuit, ideal for heavy loads and shared feeders.
• OEM-compatible engineered to pair with matching Square D QO load centers and panelboards for a seamless, dependable fit.
• Versatile application suitable for residential, commercial, and light industrial environments where reliable overcurrent protection is essential.

Ideal use cases

Use the QO2150VH to protect large branch circuits and two-pole loads in panelboards and load centers. It’s well-suited for applications such as main feeders, subpanel protection, HVAC systems, water heaters, motors, pumps, and other heavy-load circuits where dependable 150A protection at 240V is required.

How it works

When electrical fault current exceeds the set rating, the thermal-magnetic mechanism interrupts the circuit to prevent damage and reduce fire risk. The plug-in design allows the breaker to snap into the panel’s bus stabs securely, delivering a reliable, code-compliant disconnect within seconds.
