Eaton British Standard Fuse 50A, A3, 660V AC, 73 mm Fixing Centres, Offset Tag, TIS50

The Eaton TIS50 British Standard Fuse delivers robust protection for heavy-duty industrial and commercial power circuits. Engineered to BS88 A3 standards, this fuse is rated for 50A at 660V AC. Its T-type (slow blow) characteristic allows the fuse to absorb harmless inrush surges common to motor circuits or power distribution start-ups, while still ensuring rapid disconnection in the event of a sustained overload or short circuit.

Designed for maximum flexibility and safety, the TIS50 includes offset, 8.7mm wide bolted tags, which facilitate straightforward, secure mounting within industrial fuse holders or switchgear. Its fixing centres span 73 mm, supporting compatibility with a wide range of enclosures and electrical panels. The compact construction (overall length of approximately 85.5 mm and width of 21 mm) ensures easy integration with minimal strain on connected equipment.

With a high breaking capacity of up to 80kA, the TIS50 fuse is suited for challenging environments where reliability during high fault conditions is a necessity. It is widely used in industrial distribution boards, cable protection, and heavy motor protection circuits. The fuse’s ability to tolerate inrush demand makes it suitable for both general (gG) and dual (gM) motor protection applications, and it is a trusted choice for maintenance teams responsible for the safety of power circuits.

Manufactured within Eaton's renowned Bussmann Red Spot™ series, this fuse incorporates robust build quality and dependable operation. The offset tag orientation facilitates easy replacement and retrofitting within existing installations. Industrial electricians rely on the TIS50 for ensuring operational safety and meeting stringent site requirements in manufacturing, process control, water treatment plants, and power utilities.

The fuse is equipped with high rupture capacity design, compliant with CE marking standards, making it suitable for use in environments requiring adherence to international safety standards. Typical applications include electrical switchboards, industrial control cabinets, HVAC systems, and motor starter panels.

When a blown fuse must be replaced, always ensure the replacement conforms to these essential technical specifications to maintain system protection integrity. The TIS50 offers reliable performance while minimizing downtime for maintenance operations.
