This document provides technical specifications, model meanings, and application details for Chint's DZ20 and DZ15 series plastic-enclosed circuit breakers.
This document serves as a product leaflet for Chint's DZ20 Series and DZ15 Series plastic-enclosed circuit breakers. It details the model naming conventions, including codes for usage (distribution or motor protection), operating methods, and auxiliary attachments like trip units and contactors. The breakers are designed for distribution networks to provide overload and short-circuit protection for lines and power equipment, or for starting and running protection for squirrel-cage motors.
The document outlines key technical parameters, such as a rated insulation voltage of 800V, a rated working voltage of up to 400V AC, and rated currents ranging from 32A to 225A. It specifies protection characteristics, including instantaneous trip settings for distribution and motor protection applications, and provides installation dimensions and external attachment specifications for electric and manual operating mechanisms. This manual is written in Chinese.
