PRODUCT DESCRIPTION
SIEMENS 3NE1436-2 - SITOR Fuse Link, NH3, gR Type
The SIEMENS 3NE1436-2 is an NH3 size SITOR fuse link, gR type, designed for high-speed, full-range overcurrent protection of power semiconductors in industrial power electronics. Utilizing a thermal-magnetic interruption principle, this fuse provides critical circuit protection for applications including rectifiers, inverters, soft starters, and uninterruptible power supplies (UPS). It ensures system reliability and component longevity by mitigating damage from short-circuit and overload events in high-voltage and high-current industrial systems.
