HRC Type is mainly used to against electrical overload and short-circuit protection (gG), also capable to secure semiconductors (aR) and motor drives installation (aM).

Copper-made multi-section element is encapsulated in a high-intensity ceramic body which _filled with pure quartz sand as an arc extinguisher. The ends are point welded to the contact blades, the two ends of the enclosure are terminated by metal plates having high mechanical strength. Trip indicator is also equipped when overloading is occurred.
