INTRODUCTION
TNID-63 Residual Current Circuit Breaker RCD Electromagnetic Type (without overcurrent protection) is suitable for AC rated voltage 1P+N 240V and 3P+N 400V, rated current up to 100A, The types of leakage tripping are divided into AC type, A type, and B type. When personal shock or power grid leakage current exceeds the specified value, the residual current action circuit breaker can quickly cut off the faulty power supply in a very short time. Protect the safety of human body and electrical equipment, can also be used for infrequent conversion of the line starting. Products are suitable for industrial, commercial, high-rise and residential and other places.Comply with the standards: GB 16916.1, IEC 61008-1, CCC, CE certification.Residual current circuit breaker according to GB16916.1 "Household and similar applications without overcurrent protection of residual current action circuit breaker (RCCB) Part 1: General rules" design, manufacturing and inspection.
INTRODUCTION
The elevation of the installation site shall not exceed 2000m.
Ambient air temperature: the upper limit of ambient air temperature shall not exceed +40°C; The average ambient air temperature for 24h does not exceed +35°C. The lower limit of ambient air temperature shall not be lower than -5°C.
Atmospheric conditions: When the maximum temperature is +40°C, the relative humidity of the air does not exceed 50%. At a lower temperature, a higher relative humidity is allowed, such as 90% at 20°C. Special measures should be taken for the occasional condensation caused by temperature changes.
Pollution level: 2
Installation conditions: Installed in a place without shock, vibration and rain or snow attack: the upper terminal is connected to the power side, and the lower terminal is connected to the load side; The inclination to the vertical plane shall not exceed 2°. Use TH35-7.5 steel mounting rail for installation.
Installation category: Ⅱ, Ⅲ.
The external magnetic field near the place where the circuit breaker is installed shall not exceed 5 times of the earth magnetic field in any direction.
