The HVA-3 is a specialty fuse used in electrical applications. It is specifically designed for use in electrical motor controls, appliance control panels, service entrance equipment, and other applications. The HVA-3 is a two-piece fuse consisting of a base with mounting screw and lug terminal, and a cartridgetype fuse element that screws into the base. The fuse is designed to protect motors, transformers, electrical panels, and other electrical components from overloads and short circuits.

The HVA-3 specialty fuse uses an UL-97 standard Fuse-Link element as its primary operating element. This element is usually a metal-dipped, ceramic-filled type of fuse link. The Fuse-Link is rated for 60 amperes, 600 volts AC or DC, and has a 35,000 ampere interrupt capacity. The element has two contacts that allow it to be connected to the base and the load.

The working principle of the HVA-3 fuse is simple. When an overload or short circuit occurs, the Fuse-Link element heats up and eventually melts, thus breaking the electrical circuit and protecting the connected equipment. Once the overload or short circuit is resolved, a new Fuse-Link element has to be installed.

The HVA-3 fuse is designed to be used in a variety of applications in industrial, commercial, and residential settings. It is suitable for use as a motor branch-circuit protection device, and as an overload relay in motor control circuits. The fuse is also approved for use as a service entrance-circuit protector for single-phase and three-phase, 120/240-volt and 120/208-volt services. It can be also used as a meter protection device.

The HVA-3 specialty fuse is UL listed for use in many applications including motor controls, air conditioning and heating control panels, air handlers, vending machines, refrigeration equipment, and communication equipment. It is also approved for use in Class I, II, and III locations and is suitable for use in wet and damp locations.

The HVA-3 is a reliable and dependable fuse that will protect electrical motors, appliances, and other electrical components from damaging overloads and short circuits. Its Fuse-Link element and other components are of high quality and durable construction, and designed for long service life. The HVA-3 is a great choice to provide necessary protection for many electrical applications.
