Why Choose the Mersen NH32GTR400KVA-8 Transformer Fuse-Link?

The Mersen NH32GTR400KVA-8 is a high-performance DIN NH gTr fuse-link specifically engineered to protect low voltage transformers against short circuits while safely accommodating transformer energisation currents. Manufactured by Mersen, this NH3 size fuse-link delivers dependable transformer protection for industrial power distribution systems where reliability and equipment protection are critical.

Part of the trusted Mersen NH gTr 400 V AC fuse-link series, the NH32GTR400KVA-8 features live gripping lugs and a top-mounted indicator for rapid fuse status identification and simplified maintenance. Its specialised gTr time-current characteristic allows transformer magnetising inrush currents to pass while providing fast interruption of damaging short-circuit faults.

Designed for protecting 400 kVA transformers, this fuse-link has a 577 A rated current and operates on 400 V AC systems. Its high current-limiting performance helps minimise damage to transformers, cables and associated switchgear during fault conditions.
