ZW1(DW45) series intelligent universal circuit breakerDetailed product description：

Product Name: ZW1 (DW45) Series Intelligent Universal Circuit Breaker
Compliant with standard: IEC 60947-2 "Low voltage switchgear and control gear - Low voltage circuit breakers";
GB 14048.2 "Low Voltage Circuit Breakers".
Product price: negotiable
Scope of application:
The ZW1 series circuit breaker is installed as the main switch in AC 50Hz, 400V, 690V distribution networks, used for distributing electrical energy, protecting lines, and preventing power equipment from being damaged by overload, undervoltage, short circuit, single-phase grounding and other faults. This circuit breaker has multiple intelligent protection functions, which can achieve selective protection, avoid unnecessary power outages, and improve the safety and reliability of power grid operation.
