Product Description

The BUSSMANN FNM Series is a time-delay cylindrical fuse, specifically a midget fuse rated at 750 mA and 250 V AC. It features a 13/32 in x 1 1/2 in non-indicating design, identified by manufacturer part number FNM-3/4.

Frequently Asked Questions

What is the BUSSMANN FNM-3/4 fuse used for?

The BUSSMANN FNM-3/4 is a 750 mA, 250 V AC time-delay midget fuse used to protect control circuits, motors, and transformers from overcurrent. Its time-delay characteristic allows it to withstand harmless inrush currents without nuisance opening, making it suitable for industrial equipment across machining, HVAC, and material handling applications.

What are the specifications of the BUSSMANN FNM-3/4 fuse?

The BUSSMANN FNM-3/4 is a midget, time-delay fuse rated at 750 mA and 250 V AC. It has a 13/32 in x 1 1/2 in non-indicating cylindrical body. The manufacturer part number is FNM-3/4, and it belongs to the FNM series. This fuse is designed for overcurrent protection in industrial control panels and branch circuits.

How to select the correct BUSSMANN FNM series fuse for a circuit?

To select the correct BUSSMANN FNM series fuse, match the voltage rating (250 V AC) and current rating (e.g., 750 mA for FNM-3/4) to your circuit requirements. Ensure the interrupting capacity exceeds available fault current. The time-delay feature is ideal for inductive loads like motors. Always consult the manufacturer's data sheet for application-specific coordination.
