Contact block resistor BRK-001
The contact block resistor BRK -001 is designed for resistor starting and electrodynamic braking of traction electric motors in mine trolley locomotives with adhesive weight of 3, 7,10,14 t.
The block is designated for work under the following conditions:
– altitude above sea level up to 1200 m;
– environmental temperature minus 5 to plus 35 °С;
– explosion-proof mining environment, dust content up to 300 mg/m3;
– vibration of attaching points within frequency band is 1 to 100 Hz with 1 g acceleration;
– vertical and horizontal operating position.
