TIS50, Eaton 50A British Standard Fuse, A3, 660V ac, 73mm

Eaton Bussmann Series Red Spot™ Range, Type 'T' HBC Fuses

The Red Spot range of offset slotted fuses (or bolted tag fuses) from Eaton Bussmann is specifically designed for the protection of general industrial applications such as power distribution, cable protection and motor protection. Available in BS88 British Standard fuse sizes from A1 to A4, offset slotted and bolted fuses are suitable for general purpose rating (gG) and dual motor rating (gM) motor protection types.

Features and Benefits

• 2 to 200 A rated current
• Breaking capacity 80 kA up to 690 V ac
• Type A1 rated up to 550 V ac/ 250 V dc
• Type A2 rated up to 660 V ac / 460 V dc
• General purpose (gG) and dual motor rated (gM) types
• Low power dissipation
• ASTA 20 certified

As the fuse allows for the starting surge of a motor its full load current must not exceed the lesser of the dual current rating. e.g. 20 M25 must not have a continuous load of greater than 20A.

Eaton British Standard Fuse, A3, 50A TIS50

This low-voltage industrial fuse from Eaton's Red Spot range is used to provide protection to electrical circuits and improve safety for both operators and equipment.
Designed to be a sacrificial device, this component breaks the current flow to a circuit in the event of a short circuit or overload fault that could otherwise cause damage. The fuse can be used for both gG (general purpose) and gM (dual motor) protection and is a common feature of electrical wiring and switchgear systems.

Features & Benefits

• T speed to accommodate harmless inrush currents without opening the fuse
• 8.7mm wide offset bolted brackets for easy attachment to fuse holders
• Current rating of 50A for use in heavy-duty applications
• High breaking capacity of 80kA to withstand high temperatures
• Weight of 58.2g, so won't add strain to equipment

How do I replace a blown fuse?

First, identify where the outage has occurred, then unplug the equipment and turn off the power. It's important to know the specifications of the blown fuse so its equivalent can be used as a replacement. When you're sure of this, detach the fuse from its holder and insert the new one.
