Product identity

This lot contains ten MiRO RGS4 cartridge fuses rated at 63 amps and 660 volts. They are industrial aR type devices intended for low-voltage UPS and surge suppression circuits. The fuses comply with IEC safety standards and are supplied new in a single pack of ten pieces.

Compatibility checks

Verify that the equipment you are protecting specifies a 63 A aR cartridge fuse with a 660 V rating before fitting these units. Confirm the physical dimensions and bolt mounting pattern match the existing fuse holders in your UPS or surge suppression gear. Ensure the prospective short-circuit current at the installation point falls within the fuse's rated breaking capacity.

Sustained load behaviour

The aR characteristic provides fast operation under high fault currents while tolerating normal load surges without nuisance opening. During prolonged overloads the element will melt to interrupt the circuit, protecting downstream semiconductors and wiring. After any interruption the fuse must be replaced; it cannot be reset and reused.

Questions about this item

What comes in the pack and is anything else needed?

The pack contains ten MiRO RGS4 cartridge bolt fuses rated at 63 A and 660 V; no additional parts are required for basic replacement.

How do I choose the right version for my circuit?

Select the RGS4 model rated 63 A / 660 V when your low-voltage circuit requires that exact current and voltage rating under IEC standards.

What does the 63 A rating mean once the fuse is installed?

It means the fuse will carry up to 63 amperes continuously and open the circuit if the current exceeds that value, protecting wiring and equipment at up to 660 volts.
