MERSEN FERRAZ Siguranță A055D1DSR0-4R, medie tensiune, 5500V, 4R, nominală R, percutor DIN

Mersen Ferraz A055D1DSR0-4R fuse is used for circuit protection in industrial applications to safeguard equipment by interrupting excessive current. This Amp-Trap R-rated DIN style fuse is ideal for short-circuit protection in medium voltage motors. It acts as a backup fuse with a minimum interrupting rating, coordinated with overload relays. This R-rated fuse melts within 15 to 35 seconds at 100 times the R rating. This component features silver-plated brass connections for enhanced conductivity, utilising clip terminals, while the insulating body is composed of GMG construction for durability and safety.
