Square D | QOB270VH | Circuit Breaker | 70A | 2-Pole | 22kA | Bolt-On

The Square D QOB270VH circuit breaker is a rugged 70-amp, two-pole device built for bolt-on mounting in compatible Square D panels. With a 22kA interrupting rating, it’s designed to safely protect downstream circuits in demanding electrical environments—whether you’re performing maintenance, a retrofit, or a replacement.

Why the QOB270VH stands out

• Secure bolt-on mounting delivers a reliable, durable connection that stays put through regular operation and occasional panel vibration.
• Clear, strong protection—70A capacity on a 2-pole configuration protects both conductors of a 240V circuit, supporting balanced protection for critical loads.
• High fault-current tolerance with a 22kA interrupting rating, helping minimize fault energy and improve overall system safety.

Ideal applications and use cases

This breaker is well-suited for maintenance, retrofit, and replacement projects where a precise match to the panel’s spec is required. Use it to upgrade aging electrical panels, replace a failed 2-pole breaker on a 240V circuit, or reinforce protection for high-demand equipment like large appliances, shop power systems, or mid-size commercial circuits that rely on dependable overcurrent protection.

Compatibility and installation guidance

Before ordering, confirm fit and ratings for your specific panel. The QOB270VH part number is the most reliable reference for compatibility with Square D bolt-on installations. If your panel documentation specifies this exact configuration, you’re aligned with the recommended protection choice.

Practical tips for installation and longevity

• Match the breaker type (bolt-on), amperage (70A), and pole count (2-pole) to your panel’s design and downstream circuits.
• Always de-energize the panel and follow safety practices before replacement or installation.
• Consult the panel’s installation manual for any torque or sequence requirements specific to bolt-on breakers.
• Having a spare QOB270VH on hand can reduce downtime during routine maintenance or unexpected outages.

What you get

One Square D QOB270VH circuit breaker with a 70A rating, 2-pole configuration, bolt-on mounting, and a 22kA interrupting capacity—ready to integrate into compatible Square D panels that require this exact specification.
