Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The RT0-100 knife-contact fuse link is the replaceable current-limiting element of the classic RT0 enclosed filled tubular fuse system, a long-established Chinese national-standard design still widely supplied for industrial distribution protection. This unit is rated 100 A at 380 VAC in utilization class gG (general purpose), covering cable and equipment protection against overload and short circuit. The ceramic body is filled with arc-quenching quartz sand around the fuse element, and the knife/plug contacts plug directly into the matching RT0 base or switch-disconnector. Current classes within the RT0-100 frame include 30, 40, 50, 60, 80 and 100 A, so panels can standardize on one base size while varying the element rating. Breaking capacity for this series is commonly listed by suppliers at up to 50 kA. Typical duty includes motor control centers, main incomers and feeder ways of MCC panels, machine supply circuits and general low-voltage distribution where a robust, economical back-up fuse is required. Al Imran Enterprises stocks RT0 fuse links and matching bases in Lahore and supplies them to panel builders, maintenance teams and contractors across Pakistan.
