Square D QOM2150VH - 150 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D QOM2150VH — a rugged 2-pole bolt-on molded case circuit breaker engineered to protect your electrical distribution with precision. Designed for dependable branch circuit overcurrent and short-circuit protection, it integrates seamlessly into panelboards and loadcenters you rely on every day.

At a glance, this breaker delivers:

• 150 A, 240 V, 2-pole capability for robust feeder and branch circuit protection
• Bolt-on mounting for a secure, vibration-resistant bus connection that stays put even in busy electrical environments
• Thermal-magnetic trip unit providing stable, repeatable protection against both overloads and short circuits
• Compatibility with matching OEM loadcenters and panelboards, ensuring a reliable fit and coordinated protection strategy
• Versatile applications suited for residential, commercial, and light industrial settings

Why this matters in real-world installations. A bolt-on design isn't just about mounting—it's about lasting reliability. The QOM2150VH secures a solid electrical path to the bus, reducing the risk of loose connections that can lead to nuisance trips or hot spots. The thermal-magnetic trip mechanism combines fast response with predictable behavior, helping you minimize downtime and protect downstream equipment, conductors, and downstream devices.

Ideal use scenarios

Use the QOM2150VH when you need a solid, high-capacity protective device for main or feeder circuits within panelboards and loadcenters. It's well-suited for:

• New installations requiring a 150 A, 240 V, 2-pole bolt-on breaker
• Panelboard maintenance or upgrades where a matching OEM device ensures system harmony
• Residential service upgrades and commercial distribution panels needing reliable overcurrent protection
• Light industrial electrical layouts where durable, secure mounting and predictable trip behavior are priorities

Practical guidance for optimal performance

To maximize reliability, pair the QOM2150VH with compatible OEM loadcenters or panelboards and adhere to standard electrical best practices during installation. The bolt-on mounting profile is designed to deliver a rigid connection to the bus, minimizing movement and wear over time. Its 150 A rating makes it a strong fit for feeders and circuits that demand high-current protection without compromising selectivity and system coordination.

In summary, the Square D QOM2150VH is a purpose-built solution for serious overcurrent and short-circuit protection in demanding panel configurations. With its secure bolt-on design, stable thermal-magnetic trip, and OEM-compatible compatibility, it offers a dependable, long-term choice for engineers, electricians, and facilities managers who prioritize safety, reliability, and compatibility in electrical distribution.
