RT is a varistor



2. The BLK series rectifier is a fast braking rectifier. When controlling the switch on the AC side of the rectifier, rapid response of the brake can be achieved. When the appearance and wiring of the BL series rectifier need to be matched with fast braking, connect the "yellow" and "green" wires to the normally open point of the contactor. When the brake motor allows for slower braking speed, the "yellow" and "green" wires can be directly short circuited.
