Schneider Electric QOB2150VH 2 Pole Circuit Breaker

Schneider Electric QOB2150VH is a 2‑pole bolt‑on miniature circuit breaker in the QO family, delivering 150 A of overcurrent protection for 120/240 VAC circuits with a 22 kA interrupting rating. The bolt‑on design mounts in compatible enclosures and panelboards, and it provides common‑trip, thermal‑magnetic protection for both poles. This QOB‑VH model accepts copper or aluminum conductors from 4 AWG to 300 kcmil and is UL/CSA listed for use in QO load centers and NQ/NQOD panelboards. Its physical dimensions are 3.0 in wide by 4.9 in deep by 5.72 in high, reflecting its standard 2‑pole, 150 A footprint for bolt‑on installation. The unit is explicitly identified as a QOB bolt‑on breaker, differentiating it from plug‑on QO variants while maintaining 120/240 V operation and 22 kA short‑circuit current rating.
