Why Choose the Mersen NH3GTR160KVA-1 Transformer Fuse Link?
The Mersen NH3GTR160KVA-1 is a specialised NH3 size gTr fuse link engineered to protect 160 kVA distribution transformers in low-voltage electrical systems. Rated at 231 A and 400 V AC, it is designed to provide dependable transformer protection while accommodating the high magnetising inrush currents that occur during transformer energisation.
Its gTr operating characteristic is specifically matched to transformer applications. Unlike general-purpose gG fuse links, the gTr characteristic allows normal transformer energisation currents to pass without nuisance operation while providing reliable protection against overloads and short-circuit faults.
The fuse features a durable ceramic body, isolated gripping tags, standard NH blade contacts and an integrated centre indicator for rapid identification of an operated fuse. Its NH3 design with a 53.1 mm body width enables installation in compatible NH fuse bases and transformer protection assemblies.
