100A 690V 100FE FUSE

Description

The 100FE Fuse (100A, 690V) is a high-speed semiconductor protection fuse designed for fast interruption of fault currents in power electronic systems. It is widely used in VFDs, UPS systems, rectifiers, inverters, DC drives, and industrial converters to protect sensitive semiconductor components from short circuits and overload damage.

Key Features

• High-speed semiconductor protection fuse
• 100A current rating with 690V AC operation
• Class aR (partial range) protection for power electronics
• Very high breaking capacity for industrial safety
• Fast fault clearing with low I²T energy let-through
• Suitable for AC and DC circuit protection
• Compact BS88 / British standard industrial design
• Offset bolted tag connections for secure mounting
• Low power loss during normal operation
• Reliable protection for drives and converter systems
