Description
Eaton Bussmann TSL800 HBC Cartridge Fuse Link — 800A, 415V AC
The Eaton Bussmann TSL800 is a bolt-on type High Breaking Capacity (HBC) fuse link rated at 800 Amps, 415V AC, engineered for protection of heavy industrial electrical installations. With its gG utilisation category, it provides full-range protection — guarding conductors and equipment against both prolonged overloads and high-magnitude short circuit currents.
Industrial-Grade Construction
The TSL800 features a robust metallic body with bolt-hole blade terminals on both ends, enabling secure bolted connections to busbars or fuse carriers in large distribution panels and switchgear assemblies. The zinc-alloy construction ensures low contact resistance and long service life even under continuous high-load conditions.
Compliance and Standards
Manufactured in India and certified to IS:13703 (equivalent to IEC 60269), the TSL800 meets the requirements of Indian and international standards for LV fuse links. The 80kA breaking capacity rating ensures safe interruption of severe fault currents without risk of arc flash or enclosure damage.
Typical Applications
- Main incomer protection in industrial distribution boards
- Busbar protection in motor control centres (MCC)
- Transformer secondary side protection
- Generator output panel protection
- Heavy-duty feeder circuit protection in factories and substations

Eaton’s Bussmann Series is globally trusted by electrical panel builders, OEMs, and industrial electricians. The TSL range is specifically engineered for Indian voltage infrastructure (415V, 50Hz), making it a preferred choice for panel builders in Coimbatore, Chennai, and across India.
Frequently Asked Questions
Q1: What is the voltage rating of the Eaton Bussmann TSL800?
A: The TSL800 is rated for 415V AC, making it suitable for standard Indian three-phase LV distribution systems.
Q2: What does the gG utilisation category mean?
A: gG (general purpose) fuses provide full-range protection — they can interrupt both small overload currents and high short circuit currents, making them ideal for cable and feeder protection.
Q3: What is the breaking capacity of the TSL800?
A: The TSL800 has an 80kA High Breaking Capacity (HBC), sufficient for protection in high fault-level industrial installations.
Q4: What standard does the TSL800 comply with?
A: It complies with IS:13703 (Indian standard equivalent to IEC 60269) for low voltage fuse links.
Q5: What type of terminal connection does the TSL800 use?
A: It uses a bolt-on blade (tag) type connection, suitable for bolted busbar mounting in distribution panels and switchgear.
Q6: Can I use the TSL800 for motor protection?
A: The TSL800 is a gG general-purpose fuse. For dedicated motor protection (starting current withstand), an aM (motor duty) fuse is recommended. Consult Shansen Enterprises for the correct fuse selection.
Q7: Is the TSL800 available in other current ratings?
A: Yes, the Eaton Bussmann TSL series is available in multiple current ratings. Contact Shansen Enterprises for availability of other ratings in the TSL range.
