SQUARE D QOB290VHU Molded Case Circuit Breaker

QOB290VH is a Square D (Schneider Electric) QO-series molded case circuit breaker rated for 90 A, two-pole operation across 120/240 VAC, designed for bolt-on mounting in compatible QOB panelboards. It provides a 22 kA interrupt rating at 240 VAC, offering reliable protection for feeders and branch circuits against overloads and short circuits in residential or light commercial distribution. This QOB variant is built for 2-pole, 120/240 VAC service with box lugs sized for #4 to #2/0 AWG copper or aluminum conductors, enabling secure terminations in standard distribution panels. Ideal for replacing or upgrading existing protection where bolt-on QOB devices are required, this breaker integrates with Square D's QO family for consistent performance and panel compatibility.
