Fuse cartridge Eti-Polam DII gG 20A BiWtz 500V AC / 250V DC E27 (pack of 5)

Eti-Polam DII gG 20A BiWtz fuse cartridges with an E27 universal base provide replaceable overcurrent protection for low-voltage electrical installations. Rated for continuous operation up to 20 amperes, these DII gG class fuses are suitable for general protection of cables and equipment against overloads and short circuits. The BiWtz design and compatibility with standard E27 fuse holders make them suitable for use in distribution boards, control panels and other enclosures where easily replaceable DII gG protective elements are required. This product is supplied as a pack of five identical fuse cartridges.

Advantages

The fuse cartridges feature a gG characteristic for full-range protection of conductors and equipment, combining predictable melting behaviour with reliable interruption of fault currents. The universal E27 base simplifies installation and replacement in common fuse holders without special adapters. Rated for both AC and DC systems, these fuses are specified for use up to 500 V AC and 250 V DC, which allows flexible application across different supply types. Supplied in a pack of five, they reduce the need for frequent reordering for maintenance tasks.

Suitable for

• Protection of distribution boards and panel-mounted circuits
• Overload and short-circuit protection for motors, transformers and control equipment within the rated current
• Replacement of DII gG fuse elements in equipment using E27 fuse holders

How to use

Ensure the supply is de-energized and verified safe before attempting any replacement. Remove the blown fuse cartridge from the E27 holder and inspect the holder for damage or corrosion. Fit the new Eti-Polam DII gG 20A BiWtz cartridge by screwing it into the E27 socket until secure. After replacement, restore power and verify correct operation of the protected circuit. Follow local electrical codes and safety procedures during all work.

Usage recommendations

Use these fuses only within their rated current and voltage limits and match the gG characteristic to the required protection level for conductors and equipment. Replace fuses with the same utilization category and rating to maintain proper protection coordination. Store cartridges in a dry, clean environment and inspect holders periodically for secure connections and signs of overheating.
