DZ949(TO, TG) series molded case circuit breakersDetailed product description：

Scope of Application

The DZ949 (TO, TG) series molded case circuit breakers are suitable for ships and land, with AC 50Hz/Hz, rated insulation voltage of 660V, rated working voltage of AC 380 (440V) and below, and DC 250V and below circuits for infrequent connection and disconnection. Circuit breakers are equipped with overload, short circuit, and undervoltage protection devices, which can protect power equipment and circuits from damage.

Normal working conditions
1. Altitude of 2000 meters or below;
The temperature of the surrounding medium should not exceed+45 ℃;
3. Able to withstand the influence of humid sea air;
4. Able to withstand the effects of salt spray;
5 can withstand the influence of oil mist;
6 can tolerate the influence of mold;
The maximum inclination of 7 is 22.5 °;
The circuit breaker can work reliably under normal vibration of the ship;
9. Installed in a medium without explosive hazards, and without sufficient corrosion or damage to the majority of the components
The place where the gas of the edge and the conductive dust are present;
Install in a location free from rain and snow.
