Functions of PXT Type Distribution Box
Residual current protection (RSD/RCCB/RCBO): Detects leakage current and cuts off power to reduce electric shock risk. Earthing connection: Ensures proper grounding to maintain safety and system stability. It can also be applied in circuits. The PXT Station Control Unit launched by Nader stands at the forefront of this transformation. It is not a single-function device, but an intelligent control hub built on an innovative “7T” value framework, designed to fundamentally reshape the experience and operational paradigm of power. The utility model discloses a PXT distribution box, which comprises a box body, wherein a box door is arranged on one side wall of the box body, a plurality of heat dissipation fans are arranged on the box door, a plurality of heat dissipation holes are formed in one side wall of the box body. According to different usage scenarios and requirements, there are several types of distribution boxes: 1. Line wires are connected to these lugs, and the main lug panel can be used as a sub-panel when connected to a breaker from the main panel.
