Product Description
BP32 isolating switch disconnector knife switch Russia type 400A
1.1 The rated voltage of the low-voltage series open type knife switch, conversion switch, and conversion switch (hereinafter referred to as knife switch and knife shaped conversion switch) is AC 50Hz, 380V, and the rated current is 630A. In the distribution equipment of industrial enterprises, it is used as an infrequent manual connection or disconnection of lines or as an isolation switch. 1.2 Normal working conditions for knife switches and knife shape conversion switches: a. Altitude not exceeding 1000M; b. The ambient air temperature shall not be higher than+40 ºC and not lower than -30 ºC; c. The relative humidity of the air shall not exceed 85%; d. In a medium without explosion risk, and there are no gases or dust (including conductive dust) in the medium that are sufficient to corrode metals and damage insulation; e. Places without significant shaking and impact vibration.
