Heating resistance, NSYCR400W230VV, by Schneider Electric for panel box with power 400W, rated voltage 230VAC, designed for DIN rail mounting.
Heating resistance for Panel box are used to prevent condensation from forming in electrical panels and to keep the temperature from falling below a certain minimum. The purpose of the heaters is to maintain the normal operation of the devices in the panel, as well as to prevent short circuits.
For proper operation of the heater and prevention of overload, it is necessary to install additional electrical protection, as well as a thermal controller to turn the heater on and off within a certain temperature range.
