Ten spiral ceramic fuses with metal end caps

OEM Industries

OEM Industries RO21 6A gG E27 RL6-25 RL93 RLS2 5SD 5SB 500V 50KA Spiral-style ceramic fuse line protection

SKU CH-52AS-9FA77

Pack of ten 6 A gG spiral-style ceramic fuses with E27 bases rated 500 V and 50 kA breaking capacity

  • Amperage6
  • Product typeCircuit Protectors
  • 6 A rating protects circuits from overload
  • 500 V AC rating suits industrial voltage levels
  • 50 kA breaking capacity clears high fault currents
  • gG class provides general-purpose line protection
  • Spiral-style ceramic body withstands thermal stress

10-piece ceramic fuse set

This pack contains ten RO21 spiral-style ceramic fuses rated at 6 A gG for 500 V AC circuits. Each unit carries a 50 kA breaking capacity and fits an E27 base. The components are supplied new and ready for installation in compatible holders.

Suited for standard E27 fuse holders

These fuses match equipment that specifies the RO21 series with RL6-25, RL93 and RLS2 markings. They are not suitable for holders requiring a different base size, a higher current rating or a lower interrupting capacity than 50 kA.

6 A gG rating at 500 V

The 6 ampere gG classification defines the overload and short-circuit response for general-purpose line protection. Verify that the circuit design calls for exactly this rating before fitting the fuse.

Questions about this item

What socket must my fuse holder provide for the RO21 E27 fuse to fit?

The fuse uses an E27 base, so the holder needs a matching E27 socket.

Will the 6 A gG fuse coordinate with an older 25 A upstream breaker without nuisance trips?

The 6 A rating is well below 25 A, so normal load current stays within the fuse curve while the upstream breaker handles larger faults.

After installation, how can I confirm the 500 V ~ 50 kA ceramic fuse is intact?

Measure continuity across the fuse with a multimeter; a low resistance reading shows the element is unbroken.
