Product introduction

DW17 series universal circuit breaker (hereinafter referred to as circuit breaker) has the characteristics of compact structure, small volume, light weight, strong series, good interchangeability of parts, complete protection function, high technical and economic index, convenient maintenance and use, etc. Circuit breakers are suitable for circuits with rated working voltage up to 660V and 50Hz, and are used for power distribution and infrequent line switching. Protect lines and electrical equipment from overload, undervoltage and short circuit, and have classified selective protection; It can also be used to protect motors, generators and rectifier devices from abnormal conditions such as overload, short circuit and undervoltage. Kai Guanchang's conventional models of Shanghai People's Electric Appliances are: DW17-630, DW17-1600, DW17-2900 and DW17-3200.

The technical performance of the circuit breaker meets the GB/T14048.2 standard.

Normal working and installation conditions

The upper limit of ambient air temperature is not more than +40℃, the lower limit is not less than 5℃, and the average value of 24 hours is not more than +35℃.

The elevation of the installation site shall not exceed 2000m.

The relative humidity of the atmosphere should not exceed 50% when the ambient air temperature is +40℃. At a lower temperature, it can have a higher relative humidity, the monthly average relative humidity in the wettest month is 90%, and the monthly average minimum temperature in this month is +25℃, taking into account the condensation on the product surface due to temperature changes.

Pollution level: level 3.

Installation conditions: it can be installed vertically or horizontally (drawer type).

Installation category: The installation category of main circuit and undervoltage tripping coil of circuit breaker is IV, and the installation category of other auxiliary circuits and control circuits is III.
