Product Description
RS PRO 221-3689 NH Fuse is a fast-acting electrical fuse designed specifically as an NH1 centred tag fuse to provide reliable circuit protection at 250A current rating and 415V AC voltage. This fuse is constructed with a ceramic rectangular casing housing the fuse element and metal blade terminals on both ends, allowing secure connection in electrical switchgear. It meets the IEC 60269-2 standard, ensuring compliance with international safety and performance requirements.
The fuse features high rupture capacity (HRC), enabling it to safely interrupt high fault currents, protecting sensitive components and conductors from damage caused by overloads or short circuits. Its blade-type tag terminals and gG characteristic make it suitable for general purpose applications across a wide range of electrical and industrial installations.
With compact dimensions including a length of 75mm and overall length of 135mm, this NH1 fuse fits easily into fuse holders and switchgear assemblies designed for standard NH fuses. The fast-acting behaviour ensures rapid disconnection during fault conditions, minimizing risk to equipment and enhancing safety for operators.
This RS PRO fuse is intended primarily for use in electrical systems in industrial, commercial, and manufacturing environments where high reliability and consistent standards compliance are paramount. It is manufactured in India to uphold stringent quality control.
This fuse is ideal for protecting conductors and circuits in general electrical applications. HSN code and standards adherence are consistent with global and regional electrical safety codes. The fuse's robust construction supports longevity and dependable fuse operation.
Proper replacement should always match the exact current rating and fuse size to maintain system safety. A suitable fuse puller tool is recommended to safely remove and replace the fuse without damage.
