PRODUCT DESCRIPTION
SIEMENS 3NE1333-0 - SITOR Fuse-Link
This component is a SIEMENS SITOR fuse-link, specifically engineered for the protection of power semiconductors and other sensitive industrial electrical equipment. It features a square body, size 1, providing full-range protection (gR characteristic) against short circuits and overloads. This fuse is designed for applications requiring rapid and reliable interruption of fault currents, commonly found in motor control centers, soft starters, frequency converters, and uninterruptible power supplies (UPS).
