This kind of fuse is used where you need very fast protection for power electronics and semiconductor devices like diodes, thyristors, IGBTs etc. The aR class means it acts very quickly to protect sensitive components from over‑current or fault currents. It’s used in industrial converters, drives, power supply modules, inverters, etc

Because it’s a high‑capacity, high‑voltage, high‑speed fuse, it must be mounted properly (right fuse holder / bolt mount) & must match the protection characteristics needed (current, I²t, voltage).

Make sure ambient conditions (temperature, vibration) are acceptable.

Replacement fuses must match the same curve (aR) and ratings, or equipment may not be protected or may suffer damage

The innovative and comprehensive Modulostar  range of Mersen fuse-holders.
CUS101HEL series are specially designed for the protection of PV systems.
Modular fuse-holders are finger-safe under IEC and UL standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). Modular fuse-holders CUS101HEL are available in 1 pole, with or without visual blown fuse indicator.
Modulostar® range is made of tough and durable thermoplastic material.
They are especially recommended to be used in combination with Mersen fuse-links HP6M and HP10M.
