Description
Overview
The Eaton Bussmann ESD20 is a BS88 clip-on type low voltage fuse link rated 20A at 550V AC with an 80 kA breaking capacity, classified as Class gG for general-purpose protection. Part of the trusted Bussmann ESD series, this fuse link meets BS88 Part 2 and IEC 60269-2 standards and is intended for overcurrent protection in switchgear panels, motor control centres, and industrial distribution boards. Its long clip-on tag format ensures secure, positive engagement with matching fuse carriers, reducing the risk of misalignment or poor contact in demanding panel environments.

Applications & Selection Guide
The ESD20 is well suited for branch circuit and feeder protection in low voltage switchgear panels, motor control centres (MCCs), and power distribution boards operating up to 550V AC. At 20A, this fuse link is commonly selected for protecting small motor feeders (typically up to approximately 7.5 kW at 415V), instrumentation supply circuits, lighting distribution circuits, and auxiliary control power supplies in industrial panels. The Class gG characteristic provides full-range protection, meaning it will reliably clear both sustained overloads and high-magnitude short-circuit currents up to 80 kA without requiring a separate backup fuse.
When selecting this fuse for motor protection applications, verify that the 20A rating provides adequate starting current tolerance for the connected motor’s starting class. For heavy-duty or high-inrush loads, consider whether a Class gM or motor-rated fuse may be more appropriate. The 550V AC voltage rating makes the ESD20 compatible with standard 415V three-phase systems used across Indian industry as well as 525V mining and process plant systems.
Industries in India that commonly specify BS88 clip-on fuse links of this type include textile mills in Coimbatore and Tiruppur, pump set manufacturers, machine tool builders, pharmaceutical process plants, food and beverage processing facilities, water treatment infrastructure, and general engineering fabrication shops. The long clip-on tag format is compatible with a wide range of DIN-rail-mounted and panel-mounted fuse carriers designed for the BS88 F2 size.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann ESD20 fuse?
Class gG (general purpose, full-range) means the fuse is designed to protect against both overload currents and short-circuit currents across its full operating range. The lowercase ‘g’ indicates full-range breaking capacity, and ‘G’ indicates it is rated for general-purpose applications. This means a single ESD20 fuse provides complete overcurrent protection without the need for a separate backup fuse, making it the standard choice for distribution circuits and motor feeders in industrial LV panels.
What is the difference between a Long Clip-On tag and a standard BS88 fuse tag?
BS88 clip-on fuse links use spring-loaded or clip-type tags that snap positively into compatible fuse carriers, as opposed to bolted-tag or knife-blade designs. The Long Clip-On tag on the ESD20 (BS Size F2) is a specific physical format that determines carrier compatibility — it is important to match the tag type and BS size to the installed fuse carrier. Using a mismatched tag type can result in poor contact, increased resistance, or inability to fit the carrier. Always confirm your existing carrier accepts the F2 Long Clip-On format before ordering.
Can the ESD20 be used on 415V three-phase systems in India?
Yes. The ESD20 is rated for 550V AC, which comfortably covers standard 415V (line-to-line) three-phase industrial systems used throughout India. The higher voltage rating provides additional safety margin and also makes the fuse suitable for 525V industrial systems used in mining and heavy process industries. The 80 kA breaking capacity is more than adequate for the available fault levels at most Indian industrial distribution boards fed from 11kV/415V transformers.
Is the Eaton Bussmann ESD20 RoHS compliant and CE marked?
Yes. The ESD20 carries both CE marking and RoHS compliance. CE marking confirms conformity with applicable European Union safety directives, which is a common requirement for panel builders and OEMs exporting switchgear or control panels to European markets. RoHS compliance confirms the fuse does not contain restricted hazardous substances such as lead, mercury, or cadmium above permissible limits, which is relevant for environmentally conscious procurement and for systems destined for European or global markets.
What motor size can the ESD20 typically protect at 415V?
As a general guideline, a 20A Class gG fuse at 415V is typically suitable for protecting circuits feeding motors up to approximately 7.5 kW (10 HP) under direct-on-line starting, subject to the motor’s starting current profile and starting duration. For motors with heavy or prolonged starting cycles, or for star-delta and soft-starter applications, the fuse selection should be confirmed against the motor’s starting current and the fuse’s time-current characteristic curve.
