Application - System D fuse-links are designed to be replaced by non-qualified persons (mainly for household and similar applications). They are used to protect power installations against the effects of short circuits and overloads and to protect against electric shock. System D includes the entire range of five physical sizes DI, DII, DIII, DIV, DV of fuse links, ceramic and plastic sockets, and necessary accessories - heads, calibrated links, etc. D fuse links are made for Voltage [V]: voltages AC 500, 690, 750V and 1200V and DC 250V, 440V, 600V and have a rated breaking capacity of 50kA at AC current and 8kA at DC current. These fuse links have a colored operating indicator visible when the links are mounted in the fuse head and fuse base.
Advantages:
→ high Rated short-circuit capacity [kA]:,
→ slow (gL-gG) and fast (gF) characteristics,
→ wide range of rated currents from 2 to 200 A,
→ new rated currents 32A and 40A,
→ various types of incoming and outgoing clamps in sockets, → sockets with a TH rail holder.
