Power distribution box-MDS series
1. Overview
The inner outgoing lines of MDS Series power distribution box adopt
ABB Isomax S-Series molded case circuit breakers (MCCB). The
direct and compact connection of the switch and main busbar reduces
the volume of the box for easy installation. The box is made of anti-
rust high-quality electrolysis steel plate (thickness=1.5mm). with epoxy
resin electrostatic coating. The color is light grayish-white with code
RAL7032. The conductors in the box adopt tinning cooper bar with high
strength and electro conductibility, complying with GB 7251 and BS 1433
standards. The extra strong bus insulating clamp make the main bus be
more reliable to withstand short-circuit current of 50kA/s. It has been
approved by Quality system ISO 9001 to guarantee the quality is stable
and reliable in the long production process. Its technical index complies
with requirements of national and international standards. Therefore, DS-
Series is widely applies in minerals and various modern architectures,
such as civil architecture, high building, hospital, public square, station,
entertainment and sport facilities and dwelling houses.
