Eaton Bolted Tag Fuse F2, 20A, 550V AC, 68mm High Rupture Capacity ESD20

The Eaton ESD20 Bolted Tag Fuse is a specialized electrical protection component designed for demanding industrial and power distribution environments. With a current rating of 20A and a maximum operating voltage of 550V AC, this fuse provides effective protection against overcurrents and short circuits, safeguarding equipment and installations from electrical damage.

This fuse is constructed in a standard F2 size with an overall length of 68mm, making it compatible with a wide range of switchgear and fuse holders found in industrial panels. The tag width of 15mm and offset bolted tag orientation allow for a secure and robust connection, ensuring both electrical integrity and ease of installation during maintenance or replacement.

The ESD20 incorporates a high rupture capacity element, making it suitable for circuits where high prospective fault currents may be present. This attribute, combined with a fuse speed classification of 'F' (fast acting), provides excellent peak let-through current limitation. This helps protect sensitive downstream devices and maintains the coordination hierarchy between primary and secondary protection levels, with a 1:1:6 selective coordination ratio between minor and major fuses.

Certified to CE, IEC 60269, and RoHS standards, the Eaton ESD20 demonstrates compliance with international safety, performance, and environmental requirements. Its construction is consistent with industrial demands, offering reliable performance in applications such as power distribution, cable protection, panelboards, and industrial automation systems.

The fuse's robust build includes compact dimensions - 35.5mm body length, 14mm width and height, and a 13.8mm diameter - enabling efficient space utilization in dense control and distribution assemblies. The F2 format and 68mm fixing centres ensure that the ESD20 is a direct replacement for many standard tag fuses used globally.

Typical use cases include protection of electrical panels in manufacturing facilities, HVAC distribution boards, commercial building main feeds, and any environment where reliable and quick-acting overcurrent protection is required. The high rupture capacity and fast characteristic make it suitable for critical circuits where both safety and minimal system downtime are paramount.
