BR series low-ohms resistor units. RF series resistors.
BR series resistor units are intended for exploitation in DC electrical circuits voltage to 440V, and in AC circuits frequency 50 (60) Hz, voltage to 660V. Are used as additional, load, start, discharge, braking resistors and etc.
BR series resistor unit conditional shorthand structure:
BR-X1X2X3
BR – series;
X1 – rated unit resistance value fulfillment:
1 – value of resistance 0,5 Ohm
2 – value of resistance 0,75 Ohm
3 – value of resistance 1,17 Ohm
4 – value of resistance 2,06 Ohm
X2 – type of climate fulfillment Y or T due to the GOST 15150;
X3 – placing category 3 due to the GOST 15150.
BR series resistor units differ by general resistance value, separate steps resistance, rated load current.
Protection level – IP00 due to the GOST 14255.

RF series resistors are designed for BR units acquisition and can be supplied separately also. They are used as additional, load, start, discharge, braking resistors and etc. Series RF resistors consist of steel clamp with insulators mounted on it, in trenches of which fechral ribbon of high resistant is placed, taps are soldered to resistive component.
