Schneider Electric QOB290 Bolt-On Circuit Breaker

Schneider Electric QOB290 is a two-pole, 90 A QOB bolt-on miniature circuit breaker designed for bolt-on mounting in compatible panel interiors. It is rated for 120/240 VAC and provides thermal-magnetic overcurrent protection with a 10 kA interrupting rating at these voltages. The yellow-housed device is intended for use in Square D QO load centers and compatible NQ/NQOD panelboards, offering a secure bolt-on connection for reliable feeder protection. The QOB290 features a two-pole, common-trip design to disconnect both hot legs simultaneously, helping ensure safe disconnection of multi-wire circuits. As part of the Square D by Schneider Electric lineup, it is suitable for residential and light commercial distribution when installed in appropriate panelboards and mounting bases, and it is designed to fit interiors that accept QOB bolt-on breakers. Common applications include service panels, subpanels, and other distribution points in homes or small businesses where bolt-on breakers are required to meet panel design specifications.
