Industrial QOM100VH U Circuit Breaker

The Square D QOM100VH U is a bolt-on main circuit breaker from the QOM family, delivering 100 amperes of protection across two poles for 120/240-volt systems and designed to act as the primary disconnect in Square D QO/Homeline panelboards. It carries a 22 kA interrupting rating at 240 V, providing robust protection for feeders and downstream circuits, and its bolt-on mounting is compatible with panel enclosures that accept QOM main-breaker configurations, making it suitable for replacements or upgrades in existing Square D installations. Manufactured by Square D (Schneider Electric), this 2-pole device has a 100 A nominal rating and operates on 120/240 V AC, supporting standard residential and light commercial service entrances and feeder applications where a main breaker is required within a QOM-compatible panel system. Typical uses include upgrading a service to a full 100 A main breaker in existing QO or Homeline panels, replacing a worn-out main, or configuring new installations that require a 2-pole main breaker for 120/240-V service.
