Our featured products automatic transfer switch, circuit breaker, contactor, pilot light,relay, SPD, etc. with solid quality and considerable price and could equip them with enclosure. Circuit Breaker DZ47 is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. When a current is interrupted, the arc must be contained, cooled, and extinguished in a controlled way. So that the gap between the contacts can again withstand the voltage in the circuit. Electric ratings:Â a. AC: up to 63A, AC230/400V, AC50/60Hz; b. DC: up to 63A, DC110V/1P, DC125V/2P; Application: for protection of circuits from over-load and short-circuit; and for infrequent making and breaking of circuits under normal operation conditions, as well; Standard: IEC/EN 60898.
