Why Choose the Mersen US6J3I UltraSafe Class J Fuse Holder?
The Mersen US6J3I is a robust UltraSafe™ Class J fuse holder with blown-fuse indication, designed to provide reliable overcurrent protection for three-phase industrial power distribution, machinery and automation systems. It accommodates Class J fuses rated up to 60 A and combines a compact three-pole format with enhanced protection against accidental contact.
As part of the Mersen US6J UltraSafe modular fuse holder series, the US6J3I features an LED indicator on each pole to help maintenance personnel identify an open fuse quickly. This visual indication can simplify fault finding, reduce diagnostic time and support faster restoration of industrial equipment following an overcurrent event.
With ratings of 600 V AC and 600 V DC, pressure-plate terminals and standard DIN rail mounting, the US6J3I is suitable for industrial control panels, motor circuits, transformers, machinery and branch circuit protection. Its three-pole arrangement makes it particularly suitable for protecting three-phase electrical systems.

Reliable Three-Phase Circuit Protection with Fuse Status Indication
Class J fuses provide compact, current-limiting overcurrent protection for industrial equipment and branch circuits. The Mersen US6J3I securely houses three Class J fuses, helping protect conductors and connected equipment against damaging overload and short-circuit currents.
The integrated LED indicators make it easier to locate an open fuse without checking every pole individually. Combined with its finger-safe construction, DIN rail mounting and pressure-plate terminals, this makes the US6J3I a practical solution for machine builders, panel manufacturers and industrial maintenance teams.
Typical Applications
- Three-phase industrial control panels.
- Motor branch circuit protection.
- OEM machinery and production equipment.
- Industrial automation systems.
- Transformer and power-supply protection.
- Power distribution boards and switchboards.
- Manufacturing and processing equipment.
- Electrical control cabinets requiring visual fuse indication.
