The Alce AB 24 100/1A is an electrical current transformer designated by ALCE Article Code 1019402 and built to Type AB24 specifications (Drawing No 321_1 Revision E). Designed for a rated frequency of 50Hz, it features an IEC insulation level of 24/50/125kV and a thermal short-time current rating (Ith) of 10kA for 1 second, with a dynamic current (Idyn) of 2.5xIth. The continuous thermal current (Icth) is rated at 1.20xIn (120A), corresponding to a primary-to-secondary ratio of 100/1 A with the secondary terminal located at P1 [S1-S2]. The unit includes Core 1 specified at 1A 5P20 10VA. Engineered to operate within a temperature range of -25 to 40°C, this transformer is constructed for installation at altitudes up to 1000 meters. The AB 24 100/1A provides precise current reduction and core protection for medium-voltage electrical power distribution and metering systems.
