The Schneider Electric QO140M200 is a load center capable of hosting a maximum of 40 circuit breakers. It operates with a main convertible breaker rated for 200 amps and is suitable for both 120V and 240V applications. This load center is intended for single-phase, 3-wire configurations.

In terms of fault protection, it is rated for 22 kA, offering substantial safety for electrical systems under fault conditions. The design accommodates a wide range of conductor sizes, from #4 up to 250 kcmil, and is compatible with both aluminum and copper wires. The busbar is constructed from tin-plated copper, which enhances conductivity and reduces deterioration.

Housed in a welded steel enclosure, the device is rated NEMA 1, indicating its suitability for indoor installations in environments that are not subject to adverse conditions. Terminal connections on the QO140M200 utilize lugs, while grounding is managed via a dedicated ground bar. Additionally, it contains no tandem breaker slots, preserving space for standard circuit breakers only.
