Description

QO and QOB one, two and three pole thermal magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. These circuit breakers have an over center, trip-free toggle mechanism with quick-make, quick break action and positive handle indication They also have VisiTrip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit. This QO mini circuit breaker handle clamp accessory provides a means of holding one pole QO circuit brakers in the ON or OFF position.

Features

This Square D QO 1-phase main lug load center functions as a specialized, ultra-compact 30 A electrical distribution block running at 120/240 V AC. It is engineered to house and power a single single-pole branch circuit, making it the perfect choice for isolating small outbuilding utilities, dedicated workshop equipment, or remote HVAC systems without cluttering your primary panelboard.
This specialized load center features a QOM1 main frame size built to accept a standard, plug-on Square D QO single-pole circuit breaker. This configuration lets you deploy advanced standard thermal-magnetic, arc fault (AFCI), or ground fault (GFCI) branch protection up to the unit's maximum 30 A threshold while ensuring high-pressure, screw-free contact stability against the internal busbar.
Measuring just 75 mm high by 162 mm wide with a shallow 75 mm depth, this Box Number 1 enclosure features an incredibly condensed, low-profile footprint. It mounts natively to flat surfaces and includes a matching surface cover plate, allowing electricians to squeeze safe sub-panel distribution into tight utility closets, stairwells, or structural framing voids.
The factory-installed main lug connections are engineered for direct-in wiring, which significantly cuts field installation labor and wire bending times. The robust terminal lugs accept a wire cross-section range from 14 AWG to 10 AWG for copper conductors, or 12 AWG to 10 AWG for aluminum lines, ensuring flexible wiring options for standard branch feeder circuits.
The internal distribution bus is fully protected by a rugged, heavy-duty NEMA Type 1 sheet steel enclosure designed strictly for indoor utility spaces. The wrap-around steel casing shields operators from live conductors, while keeping airborne drywall dust, lint, and moisture out of the primary electrical contacts to maximize system longevity.
Built to handle severe grid anomalies safely, the load center is rated for a maximum short-circuit current rating (SCCR) of 10 kA. This high fault tolerance allows the system to contain massive localized electrical surges safely, preventing explosive arc energy from warping your interior enclosure or damaging expensive downstream appliances.
