STRO1-40L Series residual current circuit breaker with overload current protection is in conformity with the standards of IEC61009.It can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunkline.Thus it is suitable to avoid the shock hazard and fire caused by earth leakage.It can be used in circuits up to single phase 230V,three phase 400V,50 or 60Hz.
Normal working & installment conditions
1.Ambient temperature: -5ºC~+40ºC, 24 hours average temperature not exceed +35ºC.
2.Installment plance altitude: ≤2000m
3.Gas relative humidity:not exceed 50% at +40ºC, higher humidity allowed at lower temperature.
4.Pollution degree: 2 class
5.Installment condition: Mounted in the place without obvious impact or shock, no dangerous(explosion) dielectric without corrosive metal or damaging isolation gas(conductive dust).
6.Installment method: TH35-7.5 mounted rail, can be installed in distribution board, case or box. Generally mounted vertically. Tilted angle between mounting face and vertical face not exceed ±5°.
7.Mounted Category: II,III class.
