electric fuse

Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current. The drop fuse is composed of two parts: An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer. It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the load current.

High quality Electrical Fuse

Catalog symbols: EV20-(amp) 20 mm diameter EV25-(amp) 25 mm diameter EV30-(amp) 30 mm diameter Description: Eatons Bussmann® series Electric Vehicle (EV) fuses for the protection of high power battery charging and management systems up to 500 Vdc in ratings from 50 to 400 amps. Specifications: Ratings Volts - 500 Vdc Amps 50-400 A Interrupting rating Max DC 20 kA Min DC 200% Agency information Designed to: JASO D622 ISO 8820-8 Manufactured under a TS16949 quality system for compliance with automotive requirements RoHS compliant REACH declaration available upon request Packaging 20 mm fuses: 250 fuses per box 25 mm fuses: 100 fuses per box 30 mm fuses: 100 fuses per box Features: Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the needs of higher voltage battery packs. Higher interrupting rating protects high capacity battery packs needed for vehicle acceleration and range requirements. Up to ten times faster opening under high fault current conditions helps assure reliable protection of circuits and components. Requires up to 48% less space than conventional high speed fuses to help reduce space and weight. Data logging system marks each fuse with a serial number and date code for traceability of Critical to Quality characteristics. To help project the life of the fuse in your application, unique driving profiles and conditions can be simulated to verify proper fuse size and performance under a wide range of driving behaviors. Operation as low as 200% overload provides back up protection to the battery management system. Can be applied in parallel to realize greater ampacity within sizing guidelines.

Fuses : We carry brands such as EM, Bell Fuse, Cooperbussman, Littelfuse, San-O and many others.

In electronics and electrical engineering, a fuse (from the french fusée, italian fuso, "spindle" is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. Its essential component is a metal wire or strip that melts when too much current flows, which interrupts the circuit in which it is connected. Short circuit, overloading, mismatched loads or device failure are the prime reasons for excessive current.
