PZ30 (20) series modular terminal combination appliances
Product Description
The PZ30 (20) series modular terminal combination electrical appliances are suitable for controlling and distributing electrical equipment in single-phase three wire or three-phase five wire terminal circuits with an AC frequency of 50HZ, a rated working voltage of 220V or 380V, and a rated current of no more than 100A. They provide protection against overload, short circuit, leakage, and undervoltage on the line and can be widely used in modern hotels, commercial, industrial and mining enterprises, and residential buildings.

Product structure characteristics
The main structural components include covers, boxes, transparent cover doors, installation rails, conductive bars, incoming wire shields, and busbar baffles, and are equipped with neutral wires and grounding terminal blocks. The shell is divided into full type, plastic faced iron steel, and stainless steel, which can be selected according to needs. All electrical components inside the box are modular electrical components with a width of 9mm, installed on the TH35-7.5 installation rail, and can be arbitrarily combined to form various circuit schemes according to needs. The installation capacity is 2-54 units. The handle of the installed electrical component is exposed for easy operation, and other live parts are covered inside the upper cover, ensuring safe and reliable use. There are two types of installation methods: open installation (suspended) and concealed installation (embedded in the wall). The concealed box is equipped with a pre embedded box for easy installation and use by users.
