Schneider Electric QO310 Push In Circuit Breaker

Schneider Electric's QO310 is a three-pole miniature circuit breaker rated for 10 A at 240 VAC, designed for plug-in installation in QO load centers. It provides up to 10 kA of interrupting capacity at 240 V, offering protection for 240 V circuits against overloads and short circuits. The device follows the standard QO form factor, enabling straightforward replacement in compatible panels and coordinated protection with other QO breakers within a distribution system. As part of the Square D QO family, the QO310 is intended for use in standard QO enclosures where three-pole protection is required for 240 V circuits, whether in commercial or industrial installations. Its plug-in termination supports reliable, serviceable connections in compatible panel boards, and the unit is designed to fit the same mounting footprint as other QO devices for consistent installation across an electrical distribution system.
