Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The Siemens SITOR 3NE3336 is a high-speed semiconductor fuse link engineered specifically to protect power electronics. Rated 630 A at up to 1000 VAC with an aR (high-speed) operating characteristic and a breaking capacity of 100 kA, it limits fault energy so quickly that thyristors, diodes and IGBT modules survive short-circuit events that would destroy ordinary gG protection. The NH size-2 body carries slotted blade contacts secured by M10 screws, fits standard NH2 bases, switch-disconnectors and busbar systems, and includes a front operation indicator for fast visual status checks. Dimensions are approximately 149 x 72 x 60 mm with a weight around 0.79 kg; the specified ambient range is -20 to +50 degrees C. SITOR links are the standard choice inside Siemens converters and are equally at home in third-party drives, rectifier stacks for plating and electrolysis, large UPS systems, soft starters and DC feeders - anywhere semiconductor devices need dependable ultra-fast backup. Al Imran Enterprises stocks genuine Siemens SITOR semiconductor fuses in Lahore and supplies drive builders, panel manufacturers and plant maintenance teams across Pakistan.
