3ND2140 LV HRC Fuse Link, NH1, In: 200 A, aM, Un AC: 690 V, Un DC: 400 V, Front Indicator, Live Contact Lugs
Low-voltage HRC fuses are used in installation systems for distribution boards in non-residential, commercial and industrial buildings as well as in power supply companies. They therefore protect important building components and installations.
Low-voltage HRC fuses are fuse systems designed for operation by skilled persons. Non-interchangeability of rated currents and touch protection are not structurally required.
Components and auxiliary devices are designed in such a way as to ensure safe replacement of low-voltage HRC fuses or system isolation.
Low-voltage HRC fuses are available in sizes 000, 00, 0, 1, 2, 3, 4 and 4a.
Low-voltage HRC fuses are available in the following operating classes:
gG for cable and line protection
aM for short-circuit protection of switching devices in motor circuits
gR or aR for protection of power semiconductors
gS: The new gS operating class combines cable and line protection with semiconductor protection
