Designed and patented by Littelfuse, the MEGA Fuse is ideal for battery and alternator protection application and other heavy gauge cables requiring ultra-high current protection. Die von Littelfuse entwickelte und patentierte MEGA-Sicherung in Diffusionspillen-Technologie mit träger Charakteristik ist für Überstrom-Schutzlösungen von bis zu 500A konzipiert. Sie eignet sich ideal für Batterie- und Generator- Schutzanwendungen oder andere Bereiche mit sehr großen Kabelquerschnitten, die extrem hohe Anforderungen an den Überstromschutz stellen. Specifications Interrupting Rating: 2000A @ 32 VDC Voltage Rating : 32 VDC Operating Temperature Range: 40˚C to + 125˚C * Parts with asterik are short circuit protectors only. ** Voltage Drop measurements for short circuit protectors are at 75% of rated current.
