BUSS SPJ-4E100 Industrial High Voltage Power Fuse

The BUSS SPJ-4E100 is an industrial high‑voltage power fuse from Bussmann (now Eaton) engineered to protect electrical circuits in high‑voltage power systems. It is rated for 100 A and 1,000 V, making it suitable for protection in industrial distribution panels, control cabinets, and other equipment operating at voltages up to 1 kV. As part of the SPJ family, the SPJ-4E100 provides a straightforward, reliable protection solution for applications that require a 100 A device at up to 1,000 V, enabling timely disconnection of fault currents to help prevent damage to downstream components. This model is defined by its 100 A current rating and 1,000 V voltage rating, aligning with Bussmann SPJ series protection schemes in demanding industrial environments.
