Description
The FNM-30 Fuse is a time-delay (slow-blow) midget fuse designed to provide reliable overcurrent protection in circuits with temporary inrush currents, such as transformers, motors, and industrial control equipment. Its dual-element construction allows it to withstand short startup surges while protecting against sustained overloads and short circuits.
Key Features
• Time-delay (slow-blow) operation for handling inrush currents
• Dual-element design for improved overload protection
• 30A current rating for industrial applications
• 250V AC voltage rating
• High interrupting capacity for fault protection
• Compact midget fuse construction
• Ferrule-end design for easy installation
• Reliable protection for transformers and motor circuits
• Durable ceramic/fiberglass body construction
• Suitable for industrial control panels and power distribution systems
