Applications & Selection Guide
The ESD50 is engineered for general purpose overcurrent protection in low voltage power distribution infrastructure. It is commonly specified in low voltage switchgear panels, motor control centres (MCCs), and distribution boards where a reliable 50A, 550V AC protective device with high breaking capacity is required. The clip-on tag format makes it particularly well-suited for retrofit and new-build installations using F2-compatible fuse bases.
Class gG fuses like the ESD50 are the standard choice when full-range protection — covering both overload and short-circuit conditions — is needed without the selectivity constraints of back-up fuses. The 80 kA breaking capacity ensures safe interruption even in installations fed directly from medium voltage transformers where fault energy is high.
In India, the ESD50 sees regular application in textile mills, automotive component plants, chemical processing facilities, and infrastructure projects across Tamil Nadu, Maharashtra, Gujarat, and other industrialised states. Panel builders and EPC contractors in Coimbatore and across India specify this fuse for switchboards complying with IEC 61439 and related standards.

Frequently Asked Questions
What does the Class gG rating mean for the ESD50 fuse?
Class gG denotes a general purpose, full-range fuse that protects against both overload currents and short-circuit currents within a single device. Unlike back-up fuses (Class aR or aM), a gG fuse will operate across the complete range of overcurrents from just above its rated current up to its maximum breaking capacity of 80 kA. This makes the ESD50 the correct choice for circuits where a single protective device must handle all fault scenarios without relying on a downstream device to clear overloads.
Is the ESD50 suitable for use in 415V three-phase industrial systems in India?
Yes. The ESD50 is rated at 550V AC, which covers the standard 415V AC three-phase (line-to-line) distribution voltage used throughout India. The higher voltage rating provides an additional safety margin and also makes the fuse suitable for 480V and 500V systems found in some industrial and export-oriented facilities. Always verify that the prospective short-circuit current at the installation point does not exceed the 80 kA breaking capacity of this fuse.
What fuse holder or base is compatible with the ESD50 long clip-on fuse?
The ESD50 uses a long clip-on tag and an F2 BS size body. It is designed to fit F2-compatible clip-on fuse bases and holders that comply with BS88 Part 2 and IEC 60269-2. Eaton Bussmann manufactures a range of matching fuse carriers, holders, and switch-fuse units for the ESD Series. Contact Shansen Enterprises with your panel dimensions and current requirements and we will confirm the correct holder part number for your application.
Can the ESD50 be used for motor circuit protection in a motor control centre?
The ESD50 is a Class gG fuse, which provides full-range protection including overload protection. It can be used in motor circuits; however, for motor applications where high starting currents would cause nuisance tripping with a gG fuse, a motor-rated fuse (Class aM) or a suitably rated circuit breaker may be more appropriate. For direct-on-line starts with modest starting current multiples, the ESD50 at 50A may be selected for motors up to approximately 15–18.5 kW at 415V, subject to the motor’s starting duty and the coordination requirements of your panel design. Consult the Eaton Bussmann selection guide or contact our technical team for sizing assistance.
Does the ESD50 carry CE marking and RoHS compliance documentation?
Yes. The Eaton Bussmann ESD50 is CE marked, confirming conformity with applicable European Union directives, and is RoHS compliant, confirming that it does not contain restricted hazardous substances above permitted thresholds. As an authorized Eaton channel partner, Shansen Enterprises can provide genuine products along with relevant compliance documentation upon request for your project or audit requirements.
