Sieno NFIN Residual current circuit breaker RCCBs

Standard: IEC61008
Advantage
Construction Features:
* Measuring component and buckling component of products is located between enter line end and entrance line end ;
* Movement characteristic of products can not be changed with outside mechanical tool ;
* The operating organization has the free function to take off and buckle;
* Operate part can not be taken down from the shell outer of products , the shell can not influence the operating organization to
work , the accessory group which replace the feelers pressure, should guarantee the feelers pressure does not change while running.
Normal operation and mounting requirement
* Circumstance temperature -5°C ~ +40°C, average temperature within 24h not exceeding +35°C.
* Altitude above sea level less than 2000 m.
* Humidity not exceeding 50% at 40°C and not exceeding 90% at 25°C.
* Installation class II or III.
* Pollution class 2.
* Installation method DIN Rail mounting type.
* The external magnetism shall not be more than 5 times of terrestrial one.
* Product shall be installed at the place where there shall be no severe impact and vibration.
* Product shall be vertically mounted onto standard Din rail 35mm.


series Residual current circuit breaker (without over-current protection) is suitable for the line of AC 50/60Hz, voltage 240V(2pole)/415V(4pole), rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage. It can be used as infrequent changeover of the line in normal situation. It is applicable to industrial site, commercial site, tall building and civil house.
It complies with standard of IEC/EN61008.1 and GB16916.1.
