FWP-40A22F

The FWP-40A22F is a high reliability, high quality electrical specialty fuse designed for general purpose protection of DC circuits; as such, it is often used in automotive, telecommunications, industrial, and home appliances applications. The fuse is constructed from an aluminium enclosure containing a bi-metal strip, which is connected to the fuse circuit. The bi-metal strip melts and breaks the circuit when it heats up due to an excessive current flow.

The FWP-40A22F is a type 2 power limiting fuse designed to provide protection against electrical shorts and overloads in circuits containing DC motors or other inductive loads. It features high interruption capacity, allowing it to carry high currents for short periods of time. It is constructed using an aluminum alloy terminal and an anodized, non-carrying fuse body that is flame retardant to reduce the risk of ignition. The FWP-40A22F fuse also features a quick-make/break contact for high power switching applications.

The FWP-40A22F has a nominal voltage rating of 600 volts, and a nominal current rating of 40 amps. It also features a blow-open feature, which means that when an overload occurs, the fuse will quickly blow to protect the circuit. The fuse is UL 1077 Recognized and CSA Certified, and is suitable for use in Class I, Division 2 locations. Its nominal breaking capacity is 1000 amperes when used in circuits with an AC/DC frequency between 50-60 Hz.

The FWP-40A22F is designed to provide circuit protection from common electrical faults such as short circuits, overcurrents, and overloads. The highly responsive bi-metal strip creates an immediate interruption when an overload or short occurs, eliminating the need for a time-delay fuse. The FWP-40A22F fuse is also fast-acting, providing fast protection in the event of an electrical fault, while its high-interruption capacity also makes it ideal for use in motor control circuits and other applications that require frequent operation.

In conclusion, the FWP-40A22F is a general purpose, high reliability electrical specialty fuse designed for protection of DC circuits in a variety of applications. It features high interruption capacity, quick make/break contact, and a fast-acting bi-metal strip react quickly to protect the circuit from overloads and shorts. Its UL 1077 Recognition and CSA Certification render it suitable for use in a variety of locations and its nominal breaking capacity makes it suitable for use in both AC/DC circuits.
