Why Choose the Mersen HSJ1 Class J Fuse Holder?
The Mersen HSJ1 is a compact single-pole Class J fuse holder designed to provide secure mounting and dependable electrical connection for compatible industrial fuse-links. It is suitable for control panels, machinery and power-distribution equipment where reliable overcurrent protection and efficient use of panel space are essential.
Designed for professional electrical installations, the HSJ1 supports the safe integration and convenient replacement of Class J fuses. Its touch-safe construction helps reduce accidental contact with live components, while the DIN-rail mounting format simplifies installation within modern industrial enclosures and control cabinets.
With a 600 V AC/DC voltage rating and a single-pole modular configuration, the Mersen HSJ1 is suitable for branch-circuit and equipment-protection applications. The holder must be fitted with a compatible Class J fuse whose current rating and operating characteristics meet the requirements of the protected circuit.

Secure Class J Fuse Installation for Industrial Equipment
Fuse holders provide the mechanical support and electrical connections required for a fuse to operate correctly. The Mersen HSJ1 keeps the installed Class J fuse securely positioned while allowing authorised personnel to replace the fuse during maintenance.
Class J fuses are commonly selected for industrial branch circuits because of their current-limiting performance and rejection-style dimensions. The fuse fitted to the HSJ1 must be selected according to the system voltage, load current, available fault current and protection requirements of the connected equipment.
Typical Applications
- Industrial electrical control panels.
- Machinery and production equipment.
- Motor-control and automation systems.
- Power-distribution assemblies.
- Heating, ventilation and air-conditioning equipment.
- OEM electrical and electronic equipment.
