Schneider Electric QOB2100H 2 Pole Circuit Breaker

The Schneider Electric Square D QOB2100H is a bolt-on, two-pole miniature circuit breaker rated for 100 A at 120/240 V AC, designed for bolted mounting in QO-style enclosures and panelboards where a secure, hard-wired connection is required, and it is suitable for use in standard 50/60 Hz electrical systems. The QOB-H variant provides a 10 kA interrupt rating at 120/240 VAC and uses a thermal-magnetic trip to protect feeders and branch circuits up to 100 A from overloads and short circuits, making it suitable for residential, commercial, and light-industrial protection. As part of Schneider Electric’s QO/QOB family, this 2-pole device is compatible with QO load centers, NQ and NQOD panelboards, OEM mounting bases, and Speed-D switchboards, offering a bolted alternative to plug-in breakers while maintaining consistent safety standards across the family. The QOB2100H conforms to standard bolted-on configurations and is designed to meet UL 489 and CSA 22.2 certifications appropriate for its intended panel installations.
