BUSSMAN JCL-18R MEDIUM VOLTAGE FUSE T269303

The Bussmann JCL-18R is a high-performance, R-Rated current-limiting fuse designed specifically for Medium Voltage (MV) motor circuit protection. It is a "backup" fuse, meaning it is engineered to interrupt high-level short circuits, while the motor controller’s overload relays handle standard overcurrents. This fuse consists of two parallel barrels (double-barrel construction) to handle the high 390A current rating within a standard frame size.
