The BP32 low-voltage series open-type knife switch and conversion switch are primarily used in the distribution equipment of industrial enterprises for infrequent manual connection, disconnection of lines, or as electrical isolation switches.
Under standard working conditions, the ambient air temperature should be within the range of -30 ºC to +40 ºC. However, the device specifications indicate a design working range spanning from -60 ºC to +40 ºC.
It has a basic protection rating of IP00 according to GOST 14254 standards, which becomes IP32 from the drive side when properly integrated into low-voltage complete switchgear devices (NKU).
The switch should not be installed in environments with explosion risks, significant vibration or impact, or in media containing gases or conductive dust that could damage metal components and insulation.
The BP32 switch series has a rated insulation voltage (Ui) of 690V and features a rated impulse withstand voltage (Uimp) of 8.0 kV.
