DZ30-32 Miniature Circuit Breaker Type C MCB Performance Heat Resistant 1A...32A 230V Circuit Breaker
Application
Circuit breakers perform 3 key functions: protection, switching, and monitoring. Circuit breakers are designed to “break” (discontinue) the flow of electricity to protect people and equipment when current reaches an unsafe level due to overload, short circuit, or other electrical faults. . Different types of circuit breakers may include design features that provide ground fault and/or arc fault protection for residential use, or with metering and alarm functions, and remote on/off control for commercial and industrial use. We are your one source solution for all your circuit breaker and equipment needs.
The DZ30-32 series miniature circuit breaker is applicable to the circuit an alternating current of 50Hz, rated voltage of 230V, and rated current up to 63A for overload protection and short circuit protection and also for not-frequent operational transformation in the circuit under normal condition.This product can be applied to various places such as industrial, commercial, and tall buildings, and residential houses. The product meets the standards of GB10963.1, IEC60898-1.
