Cooper Bussmann FNM Series 30 Amp Midget Fuses (2-Pack)

The Bussmann series BP-FNM-30 pack contains 13/32" x 1-1/2" supplemental, fast-acting, time-delay fuses. It's often used to protect control circuit wiring, motor control transformers and small motors in industrial, commercial, agricultural, heating, ventilating and air conditioning equipment.Supplemental fuses provide additional protection for electrical circuits beyond what is offered by branch rated devices. They are not intended for branch circuit protection but are designed to protect specific components or equipment within an electrical system. This is particularly important when protecting sensitive equipment from overcurrent or where precise overcurrent protection is necessary.As a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse). This is necessary for equipment that regularly experiences short-term power surges, such as when a motor or transformer starts up. The time-delay feature allows an inrush current from the motor or transformer to start without opening but still protects against sustained overloads and short circuits. This also allows you to reduce the need to replace expired due to normal inrush overloads.For superior protection, we recommend upgrading to the Bussmann series Low-Peak LP-CC fuses.

• Ensures protection of 125- and 250-volt inductive circuits
• Ideal for use in meter, general-purpose circuits, and more
• Dual-element time delay helps eliminate circuit interruption
