High Breaking Capacity 120kA NH00 NH‑Type Fuse‑link gL‑gG Industrial Fuse
24 Hours online(Perfessional response)
This NH00 size 00 knife‑blade HRC fuse‑link complies with IEC60269‑2 and DIN43620 standards, widely known as NT00 / RT16‑00 industrial fuse. Rated for AC 690V and DC up to 440V, current range covers 2A‑160A with gG general‑purpose cable protection and optional aM motor‑protection version. It delivers high breaking capacity up to 120kA for reliable short‑circuit and overcurrent protection in low‑voltage power distribution panels, switchgears and motor control circuits.

Applications
Protection against overload and short-circuit in electric lines (type gG), also available for protection of semiconductor parts and equipments against short-circuit (type aR) and protection of motors (type aM).
Design Features
Variable cross-section fuse element made from pure copper or silver sealed in cartridge made from high-duty ceramic; Fuse tube filled with chemically treated high-purity quartz sand as arc extinguishing medium. Dot-welding of fuse element ends to the terminals ensures reliable electric connection and forms insert knife type contacts. Indicator or striker may be attached to the fuse link to show cutout of fuse or to give various signals and to cut the circuit automatically.
