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.

• 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.

This Eaton British Standard fuse protects your electrical equipment and motors from short circuits and current overloads. The bolted metal tags on either end of the cylindrical body fasten to a circuit and conduct power through the fuse. If the current continuously exceeds the maximum capacity then the metal strip inside the fuse melts and the circuit is physically broken. This is a reliable, material-based way to break your circuit without having to rely on a digital circuit breaker. General-purpose (gG) and dual motor rating (gM) motor-protection devices commonly use this type of fuse.

• 100A (amperes) maximum current capacity for dependable use with large low-voltage currents
• 80kA (kiloamperes) breaking capacity ensures breaking the current is safe and won’t destroy your equipment or cause fire or shock hazards
• Low power dissipation ensures circuit power is maintained through the fuse

The T-speed fuse has a slow-burning speed, so it allows for some over-voltage but breaks when the level becomes critical. It has a high-rupturing capacity (HRC), which ensures the circuit is not just going through a momentary spike or needs to be turned off, helping to avoid unnecessary current interruptions.
