FAQ

What is the function of the “striker” on this Legrand 0 185 80 fuse?

The striker is a small, spring-loaded pin that is released when the fuse element melts. It provides a mechanical force that can operate a microswitch or a trip bar in a fuse-switch disconnector. This allows for remote electrical indication that the fuse has operated or can trip all three phases in a three-phase system, preventing single-phasing of motors.

What does the “gG” characteristic mean for this fuse?

The “gG” designation indicates a general-purpose fuse characteristic according to IEC 60269. ‘g’ stands for a full-range breaking capacity fuse (protecting against both overload and short-circuit currents), and the second ‘G’ specifies its use for the protection of general applications, such as cables, lines, and equipment without high inrush currents.

Is this NH4 fuse link suitable for protecting semiconductor devices?

No, this gG-class fuse is not designed for the protection of sensitive semiconductor devices like thyristors, IGBTs, or diodes. For such applications, a fuse with an “aR” or “gR” (ultra-rapid) characteristic is required to react quickly enough to prevent damage to the components.
