Applications & Selection Guide
The Eaton Bussmann ED315 is best suited for general purpose overcurrent protection in low voltage switchgear panels, motor control centers (MCCs), and distribution boards operating on 415 V AC three-phase systems — the standard supply voltage for industrial facilities across India. Its 315 A rating covers feeder circuits, main incomer protection, and large motor branch circuits where high continuous current capacity is essential.
As a Class gG fuse, the ED315 provides full-range protection, meaning it can safely interrupt fault currents from small overloads up to its 80 kA breaking capacity. This makes it appropriate for protecting cables, busbars, and switchgear that may be exposed to high prospective short-circuit currents in utility-fed panels. Engineers selecting between gG and gM classes should note that gG is the correct choice where general cable and equipment protection — rather than motor-starting surge tolerance — is the primary requirement.
In India, the ED315 sees wide use across industries including automotive manufacturing, textile mills, chemical processing plants, food and beverage facilities, infrastructure projects, and commercial building services in cities such as Coimbatore, Chennai, Pune, Ahmedabad, and Mumbai. Panel builders and electrical contractors who require a robust, standards-compliant fuse link for high-current LV distribution applications will find the ED315 a reliable and readily available solution through Shansen Enterprises.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann ED315 fuse link?
Class gG denotes a general purpose, full-range fuse capable of breaking any current that causes it to melt, from small sustained overloads right up to its rated breaking capacity of 80 kA. The ‘g’ prefix indicates full-range breaking capability, while ‘G’ identifies general purpose cable and equipment protection. This distinguishes it from gM or aM types, which are optimised for motor-starting conditions. The ED315 gG classification means it is the correct choice for protecting feeders, cables, and distribution equipment in low voltage panels rather than applications requiring high motor-inrush tolerance.
Is the Eaton Bussmann ED315 compatible with 415 V AC three-phase systems used in India?
Yes. The ED315 is rated at 415 V AC, which matches the standard three-phase low voltage supply voltage used throughout India (415 V line-to-line, 240 V line-to-neutral). This makes it directly applicable to industrial and commercial electrical installations without any derating or voltage compatibility concerns. Engineers do not need to apply additional voltage correction factors when specifying the ED315 for standard Indian LV distribution systems.
What fuse base or carrier is required for the Eaton Bussmann ED315?
The ED315 is a BS Size B3/B4, bolted type, centre tag single slot fuse link. It must be installed in a compatible Eaton Bussmann BS88 fuse base or carrier that accepts the B3/B4 bolted-type form factor with a centre tag single slot configuration. Using the correct matched carrier is essential for safe electrical contact, correct current rating, and compliance with BS88 Part 2 and IEC 60269-2 standards. Contact Shansen Enterprises to confirm the correct carrier part number for your specific panel or switchgear application.
What is the breaking capacity of the ED315 and why does it matter for panel design?
The ED315 has a breaking capacity of 80 kA. This is the maximum prospective fault current the fuse can safely interrupt without damage to the fuse holder, switchgear, or surrounding equipment. When designing low voltage panels, electrical engineers must verify that the prospective short-circuit current (PSCC) at the point of installation does not exceed this figure. In most Indian industrial installations fed from utility transformers, the PSCC at LV distribution boards is well within the 80 kA limit, making the ED315 suitable for main incomer and feeder protection in typical switchgear and MCC applications.
Does the Eaton Bussmann ED315 carry CE and RoHS compliance?
Yes. The ED315 is CE Marked, confirming conformity with applicable European directives for low voltage equipment, and is RoHS Compliant, meaning it does not contain restricted hazardous substances such as lead, mercury, or cadmium above permitted threshold levels. These compliances make the ED315 suitable for export projects, CE-required installations, and facilities with environmental and sustainability requirements. It is also IEC Rated under BS88 Part 2 and IEC 60269-2.
