Product Overview

ATS dual power switch cabinet is used in situations where equipment cannot be powered off for a long time, such as firefighting equipment. So in addition to the electricity needed at that time, a backup power source is also needed for protection. At this point, a dual power distribution box is needed. Once the main power supply is cut off, it will automatically switch to the backup power supply to ensure uninterrupted operation of the equipment. According to the standard: GB/T7251.12-2013

Product Features

The main components of the product include dual power switches, molded case circuit breakers, contactors, relays, busbars, insulation components, instruments, indicator lights, nameplates, transformers, and other main components and shell components

This product is an indoor enclosed distribution box, with a box structure made of thin steel plates bent and welded together. It has an inner and outer door structure, with the front facing up, down, left, and right doors. The door is equipped with measuring instruments such as voltmeters and ammeters, as well as insertion holes for operating handles. The box contains electrical components such as operating appliances, signal appliances, and knife switches. The upper and surrounding protective plates of the box are detachable, and there are cable clamps for fixing cables inside the box. The distribution box can be installed against the wall as needed, and the incoming and outgoing cables are introduced from the bottom. If users have special needs, they can also enter the wire tapping hole on the top cover plate of the box or install a separate busbar room. This product is widely used in distribution systems without special requirements.
