What is Littelfuse used for?
Littelfuse battery management devices provide methods of conserving battery power, protecting against over-discharge, combining and protecting auxiliary equipment such as liftgate motors.
Where are Littelfuse products made?
Littelfuse, Inc is an American electronic manufacturing company headquartered in Chicago, Illinois. The company primarily produces circuit protection products but also manufactures a variety of electronic switches and automotive sensors.
What are the 3 types of fuses?
Different Types of Fuses – Constriction, Working & Characteristics DC Fuses. AC Fuses. Cartridge Fuses. D – Type Cartridge Fuse. HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse. High Voltage Fuses. Automotive, Blade Type & Bolted Type Fuses. SMD Fuses (Surface Mount Fuse), Chip, Radial, and Lead Fuses.
What is Rewirable fuse?
Rewireable Fuses are the fuse carriers that contain a length of fuse wire, which is wrapped around the terminals, covering the space between carriers and pins, to complete the circuit. It is used in interrupting the circuit in conditions like over-current or short-circuits.
What is the difference between an AC and DC fuse?
The main difference between a fuse's AC and DC ratings is the ability to stop the arcs that form when the fuse blows. DC arcs are harder to stop than AC arcs, so you will often see fuses that are only rated for 32VDC.
