MVnex550

Summary

MVnex550 indoor AC metal enclosed switchgear (hereinafter referred to as MVnex550 switchgear) is a subsidiary of MVnex, A complete set of power distribution for 12kV three-phase AC 50Hz single busbar and single busbar segmented systems with very small dimensions Equipment. MVnex550 has the functions of preventing loaded push-pull circuit breaker handcart, preventing accidental opening and closing of circuit breakers, and preventing, When the grounding switch is in the closed position, close the circuit breaker to prevent accidental entry into the live compartment and to prevent accidental entry during live operation The "five prevention" interlocking function of the grounding switch is equipped with Schneider Electric's HVX indoor medium voltage fixed seal type Air circuit breaker handcart is a high-performance distribution equipment.

The size design of MVnex550 saves customers a lot of distribution space and is mainly used for commercial and industrial construction Buildings, real estate, data centers, and other industrial power grids that require miniaturization in substation locations.
