The light grey finish integrates into standard panel layouts and helps maintain a neat, professional appearance while meeting practical requirements for fuse replacement and maintenance.

Suitable for (tasks / use cases)

• Mounting Class J fuses in three-phase distribution circuits
• Electrical protection and isolation in industrial control panels
• Replacement or retrofit in switchgear and distribution blocks
• Applications requiring up to 600 V and up to 100 A per pole

When it may not be suitable

This fuse holder is intended specifically for Class J fuses and is not appropriate for other fuse types or non-standard fuse dimensions. It is designed for up to 600 V and 100 A ratings; systems with higher voltage or current requirements will need components rated accordingly. Also, installations requiring integrated indication, auxiliary contacts, or electronic monitoring will require additional devices not provided by this basic fuse holder.

Key specifications

• Number of poles: 3
• Compatible fuse class: Class J
• Rated voltage: 600 V
• Rated current: 100 A
• Color/finish: Light grey
• Mounting: panel/switchgear compatible

How to use

Install the fuse holder into the designated panel location following the enclosure manufacturer's mounting provisions and local electrical codes. Fit Class J fuses into each pole, ensuring correct orientation and firm seating to obtain reliable contact. Tighten any terminal connections to the torque values recommended by the system documentation and verify continuity and insulation as part of commissioning. For maintenance, de-energize the circuit before removing fuses and replace with equivalent Class J fuses rated for the intended voltage and current.

What to consider before purchase

• Confirm compatibility with Class J fuse dimensions and ratings required for your system
• Verify that the 600 V / 100 A ratings meet your application limits
• Ensure the holder's mounting style matches your panel or switchgear layout
• Plan for safe access for fuse replacement and maintenance

Usage recommendations

Use the Rittal SV 9345.100 with certified Class J fuses of matching ratings, follow local electrical standards for installation and torque settings, and always de-energize circuits before service to ensure safe and reliable operation.
