NH-U — NH fuse bases, partitions, covers and accessories
Country: Germany · Model: NH-U
NH-U is a system of bases for NH fuses and semiconductor links with blade contacts in distribution boards, converter cabinets and energy storage cabinets. The bases come in single- and three-pole versions for NH1 and NH2 at AC 690 V, as well as at AC/DC 1000 V and DC 1000 V for PV plants and battery systems. The program includes partitions, covers, a removable handle and signal switches.

Description
NH-U bases for AC 690 V have part numbers 2100301 (NH1, 1 pole), 2100401 (NH2, 1 pole) and 2100403 (NH2, 3 poles). For AC/DC 1000 V, 2155601 is made, and for DC 1000 V 2155628 and 2155728. URB-U NH00 bases for AC 1000 V in size DIN80, including with covers 2118901 and 2118908, are intended for URB semiconductor links with screw fixing. NH-U partitions for NH1 and NH2 (2500301, 2500401) increase the creepage distances between poles, and protective covers 2100301-26 and 2100401-26 cover the live parts of the AC 690 V bases. The removable handle NH-Z 2200102 for AC 1000 V works with sizes NH000–NH3 and safely removes the links. NH-GL signal switches transmit a signal about operation, AC 250 V / 5 A for 2800202 and AC 5 V / 1 mA for 2800204. The bases and links conform to IEC 60269 / VDE 0636.
How to choose
The size NH1 or NH2 and the number of poles define the base, and the voltage is chosen according to the network, AC 690 V, AC/DC 1000 V or DC 1000 V. For PV plants and battery systems the DC 1000 V version is taken. Semiconductor links require URB-U, and the links themselves are selected among ULTRA rapid (UR) and NH (LV). For storage systems at DC 1500–2000 V, see BESS aBat / gBat.
