Why Choose the Mersen D210338 12.5 A Time-Lag Ceramic Cartridge Fuse?
The Mersen D210338 is a high-performance 5 × 20 mm time-lag ceramic cartridge fuse designed to provide dependable overcurrent protection for electrical distribution circuits, industrial machinery and control equipment. Part of the established Mersen 5HT IEC Miniature Fuse series, it protects equipment against sustained overloads and short circuits whilst tolerating temporary start-up currents.
Its time-lag operating characteristic allows brief current surges to pass without unnecessary fuse operation. This makes the D210338 particularly suitable for motors, transformers, power supplies and other inductive loads that may draw a high current when first energised.
Rated at 12.5 A and 250 V AC, the D210338 provides an AC breaking capacity of 1,500 A. Its durable ceramic body and compact 5 × 20 mm dimensions support reliable installation in compatible miniature fuse clips and holders.

Reliable Protection for High Start-Up Currents
Motors, transformers and power supplies can draw a short-duration current significantly above their normal operating level when energised. A time-lag fuse is designed to tolerate this temporary surge whilst continuing to disconnect the circuit if an overload persists or a short circuit develops.
The Mersen D210338 combines a high current rating, ceramic construction and substantial breaking capacity in a compact miniature fuse format. It is suitable for industrial equipment, electrical distribution circuits and OEM assemblies requiring dependable overcurrent protection.
Typical Applications
- Industrial electrical distribution circuits.
- Motor control equipment.
- Transformers and power supplies.
- Industrial control panels.
- Automation and production machinery.
- OEM electrical equipment.
