Product Description
MCCB DZ15
Scope of application:
DZ15 series molded case circuit breaker (hereinafter referred to as breaker) is applied in the circuit with AC 50Hz, rated voltage up to 380V and rated current up to 100A. As the purpose of distributing power energy. It also can be used to protect the circuit and motor from overload and short-circuit as infrequent transformation of the circuit and the starting of motor.
This product complies with GB140048.2, GB14048.4, IEC60947-2 and IEC60947-4 standards.
Normal working conditions and installation condition:
1. Maximum ambient air temperature does not exceed 40 ° C, and the minimum is not less than -5 ° C. The average temperature does not exceed 35 ° C within 24h;
2. The altitude of installation site does not exceed 2000m;
3. Relative humidity of the surrounding air temperature is less than 50% at 40 ° C. At a lower temperature, it can be a higher relative humidity. For example at 20 ° C, it is up to 90%. When it occurs the occasional condensation due to temperature changes, appropriate measures should be taken.
4. Pollution degree: Class 3;
5. Installation category: Main circuit of circuit breaker is ClassIII. Control and auxiliary circuits are ClassII.
Structure and working principle:
This series circuit breaker consists of contacts, operation mechanism, hydraulic electromagnetic release, arc extinguishing mechanism and plastic shell. When the protected circuit or motor occur overload and short circuit, the circuit breaker can be reliably broken. Multi-poles breaker can be Agency linkage. As long as a pole occur overload action, it will make all poles simultaneously break.
Main technical parameter is shown in Table 1.
Protection characteristic of overcurrent release used in power distribution protection is shown in Table 2.
Protection characteristic of overcurrent release used in motor protection shown in Table 3.
We also produce many various of circuit breakers.
