Description
Overview
The Eaton Bussmann ED250 is a bolted-type, low voltage BS88 fuse link from the Bussmann TSF/TSK series, rated 250A at 415V AC with an 80 kA symmetrical breaking capacity. Conforming to BS88 Part 2 and IEC 60269-2, this Class gG fuse link provides full-range overcurrent protection for cables, busbars, and equipment in low voltage power distribution systems. Its centre tag single slot design in BS Size B3/B4 ensures compatibility with widely used fuse carriers and bases across industrial switchgear in India.

Applications & Selection Guide
The ED250 is ideally suited for main incomer and outgoing feeder protection in low voltage distribution boards (LDBs), motor control centres (MCCs), and power control centres (PCCs) operating on 415V AC, 3-phase systems. At 250A, it protects large cable runs, busbar trunking systems, and sub-main feeders where both overload endurance and high fault-current interruption are critical design requirements.
As a Class gG fuse, the ED250 provides full-range protection — responding to sustained overloads as well as high prospective short-circuit currents up to 80 kA. This makes it appropriate where the upstream fault level at the point of installation is significant, such as near transformer secondaries or close-to-source switchboards. Engineers should verify that the prospective short-circuit current (PSCC) at the installation point does not exceed 80 kA and that the fuse carrier or base is rated for B3/B4 BS sizing.
In Indian industries — including automotive manufacturing, textile mills, cement plants, food processing units, pharmaceuticals, and infrastructure projects across Tamil Nadu, Maharashtra, Gujarat, and Andhra Pradesh — BS88 gG fuse links remain a preferred device for main circuit protection due to their predictable time-current characteristics and straightforward replacement. The ED250 is a direct fit for panel builders and electrical contractors specifying Eaton Bussmann components in compliance with IS/IEC standards.

Frequently Asked Questions
What is the breaking capacity of the Eaton Bussmann ED250 fuse link?
The ED250 has a breaking capacity of 80 kA at 415V AC. This means it can safely interrupt fault currents up to 80 kiloamperes, making it suitable for use in switchboards and distribution panels installed close to transformer secondaries or other high fault-level supply points.
What fuse class is the ED250 and what does Class gG mean?
The ED250 is rated Class gG, which stands for general purpose, full-range fusing. A gG fuse protects against both sustained overloads and short-circuit faults across the full range of overcurrent conditions. It is the standard class used for cable and general circuit protection in low voltage distribution systems per IEC 60269-2 and BS88 Part 2.
Which fuse carrier or base is compatible with the ED250?
The ED250 fits B3/B4 BS-size fuse carriers and bases from the Eaton Bussmann TSF and TSK series. Always confirm that the fuse carrier is rated for at least 250A continuous current and 415V AC. Using a correctly rated, matched fuse carrier is essential for safe operation and to maintain the published breaking capacity of 80 kA.
Is the Eaton Bussmann ED250 suitable for motor protection applications?
The ED250 is a Class gG general purpose fuse and is well suited for protecting the supply cables and feeders feeding motor control centres (MCCs) and distribution boards at the 250A rating. For direct motor branch-circuit protection where high inrush currents must be tolerated without the fuse operating, a Class aM (motor duty) fuse may be more appropriate. Consult Shansen Enterprises for guidance on selecting the correct fuse class for your specific motor or feeder application.
What standards and certifications does the ED250 comply with?
The Eaton Bussmann ED250 complies with BS88 Part 2 and IEC 60269-2, the internationally recognised standards governing low voltage fuse links. It carries IEC certification, is CE Marked confirming conformity with applicable European directives, and is RoHS Compliant, confirming restriction of hazardous substances in its construction.
