Fuseholder Rittal SV 9345.015, Class J, 30 A, 600 V, light grey

Rittal SV 9345.015 is a Class J fuseholder designed for 30 A rated current and up to 600 V rated voltage. Finished in light grey, this three-pole fuseholder provides a compact and secure mounting solution for cartridge fuses in control cabinets and distribution panels. It is intended for installations where reliable overcurrent protection and straightforward fuse replacement are required.

Advantages

The fuseholder offers secure mechanical retention and clear pole separation to reduce the risk of short circuits during maintenance. Its compact design saves space in electrical enclosures while maintaining accessibility for routine inspections and fuse changes. The light grey finish provides a neutral appearance that integrates with typical industrial panel interiors.

Suitable for

• Three-pole industrial control cabinets and motor control centers
• Distribution boards where Class J cartridge fuses are specified
• Applications requiring a 30 A fused protection at voltages up to 600 V
• Environments where compact, replaceable fuse solutions are preferred

When it may not be suitable

This fuseholder is not appropriate where fuse types other than Class J cartridge fuses are required, or where higher continuous currents or voltages beyond 30 A and 600 V are needed. It may also be unsuitable for single-pole applications if only one-phase protection is required and a different form factor is preferred.

Key specifications

• Rated current: 30 A
• Rated voltage: up to 600 V
• Poles: 3 (three-pole configuration)
• Fuse class compatibility: Class J cartridge fuses
• Color/finish: light grey
• Mounting: panel/enclosure mounting for compact electrical panels

How to use

Install the fuseholder in the panel cutout or mounting rail according to the enclosure layout and wiring diagram. Connect supply and load conductors to the appropriate terminals, ensuring correct torque on terminal screws and proper strand preparation. Insert Class J cartridge fuses into each pole, verify correct seating, and restore power. For fuse replacement, de-energize the circuit, open the enclosure, withdraw the blown fuse and replace it with the specified Class J fuse of the same rating.

What to consider before purchase

• Confirm compatibility with Class J cartridge fuses and the required fuse ratings for your circuit
• Verify that 30 A and 600 V ratings meet the electrical protection and regulatory requirements of the installation
• Ensure the three-pole form factor and physical dimensions fit your panel layout and mounting method
• Check accessibility for maintenance and safe isolation procedures in your enclosure

Usage recommendations

Use approved Class J fuses that match the system’s fault-current characteristics and follow local electrical codes. Always de-energize circuits before performing fuse replacement or maintenance and use appropriate personal protective equipment when working inside live panels.
