TNID Residual Current Circuit Breaker

Scope of Application TNID-63 Residual Current Circuit Breaker is used for the circuit of AC 50Hz, rated voltage of 230V for 2 poles, 400V for 4 poles, rated current of 63A, when the personal electric shock or grid leakage current exceeds the specified value, the residual current action circuit breakers cut off the trouble power quickly to protect the personal and electrical equipment, it also can be applied to infrequent transfer and start of the circuit. TNID-63 RCCB Circuit Breaker are applicable to industrial, commercial, high-rise and civil residence and other places. Meet the standards: GB 16916.1, IEC 61008-1, obtain CCC, CE certification. Normal operating conditions and installation conditions The elevation of the installation site is not more than 2000m. Ambient air temperature: -5℃~40℃, and average temperature in 24h below +35℃. Atmospheric conditions: Atmospheric relative humidity at ambient air temperature is + 40℃ for not more than 50%, in the low temperature can have higher relative humidity. Consider the temperature changes in product on the surface of the gel and take special measures. Pollution degree: 2 Installation conditions: Installed in the place without simpact vibration and invasion of rain and snow: the upper-terminal connects the power, the lower terminal connects load; the inclination of the vertical plane is not more than 2 °. Mounted on the TH35-7.5 steel rail. Installation categories: Ⅱ, Ⅲ level. The external magnetic field in the vicinity of the circuit breaker installation site does not exceed 5 times of the geomagnetic field in any direction.
