Eaton British Standard Fuse F1 Size 20A 550V AC High Rupture Capacity NSD20

Eaton NSD20 is a British Standard Fuse F1 Size designed for circuit protection in industrial and commercial environments. Rated at 20A and 550V AC, it prevents damage caused by current overloads and short circuits by melting its internal wire safely.

This Eaton Bussmann HRC fuse features an F1-sized compact cylindrical body with bladed tags for easy and secure installation into standard fuse holders. The physical melting mechanism operates independently of digital controls, ensuring reliable circuit interruption under fault conditions.

With a high rupture capacity of 80kA, the NSD20 effectively minimizes fire risk and equipment damage by safely breaking the circuit during overloads or short circuits. Its low temperature rise makes it ideal for high-density mounting where space and heat dissipation are critical factors.

Suitable for three-phase electrical systems and compliant with type 2 coordination as per IEC 947-4, this fuse is widely used in industrial, manufacturing, electrical switchgear, HVAC, and water treatment installations.

Technical features include a tag width of 12.7mm, blade tag type, overall length of 58.5mm, and height of 34.6mm. The fuse size is F1 and it belongs to the Eaton Bussmann series known for durability and performance.

Use this Eaton NSD20 British Standard Fuse to protect wiring systems, circuit breakers, and electrical equipment effectively. Trust the high rupture capacity and reliable mechanical operation to safeguard your installations.

The fuse has a 20A current rating suitable for larger low-voltage circuits. F1 size with bladed tags for quick installation in fuse holders. High rupture capacity of 80kA ensures safe operation under fault conditions. Compact cylindrical design minimizes power loss and improves energy efficiency.
