FUSE 1000A 690V EATON 170M5166

Product Description

The 170M5166 is a square-body, high-speed fuse-link designed for protecting power semiconductors such as inverters, rectifiers, and DC bus systems. It belongs to Eaton’s Bussmann aR class fuses, which are engineered for extremely fast fault interruption and very low let-through energy to safeguard sensitive electronic components.

This fuse is commonly installed in medium and high-power industrial systems where fault currents can reach very high levels and rapid isolation is critical to prevent catastrophic equipment failure.

Key Features

• High-speed semiconductor protection fuse (aR class)
• Square body DIN 2 construction with bolted blade terminals
• Extremely fast current-limiting performance
• Very low I²t let-through energy for semiconductor safety
• High breaking capacity up to 200 kA
• Suitable for AC 690V industrial power systems
• Designed for drives, inverters, rectifiers, and DC link protection
