Product identity

The OEM Industries RO21 E27 RL6-25 RL93 RLS2 5SD 5SB is a spiral-style ceramic fuse rated at 20 amps and 500 volts. A pack contains ten pieces designed for circuit protection in electrical supply systems.

Compatibility check

Verify that the existing holder accepts an E27 base and that the circuit operates at or below 500 volts alternating current. Confirm the required breaking capacity matches 50 kiloamps and that the gG characteristic suits the load type.

Upgrade context

These fuses replace worn or blown ceramic links of the same RO21 series and ratings. The step up is justified when the original parts show ageing or when a spare stock of ten ensures rapid restoration of line protection.

Questions about this item

What comes in the box and do I need anything else to install these fuses?

The pack contains ten RO21 spiral-style ceramic fuses rated 20 A, 500 V ~ and 50 kA breaking capacity. They fit standard E27 fuse holders; no extra parts are required if the holder is already in place.

How do I choose between the different codes shown — RO21, RL6-25, RL93, RLS2, 5SD, 5SB?

Those codes describe a single fuse variant: RO21 is the series, E27 the base, RL6-25 and RL93 are dimensional references, RLS2 the body style, and 5SD 5SB the gG characteristic. Order this exact combination for 20 A protection.

What does the 50 kA rating mean when the fuse is actually in my circuit?

It means the fuse can safely interrupt up to 50 000 amps of fault current at 500 V AC without rupturing, so it will clear a severe short-circuit on a 20 A circuit without damage to the surrounding equipment.
