DEVICE TESTING INPUT PROTECTIVE AUTOMATIC SWITCHES

摘要

electrical engineering, tests of protective automatic switches preventing ignition of electric wires of low-voltage networks in case of their short-circuiting. SUBSTANCE: serviceability of protective automatic switch is tested by placement of plug of shunting unit incorporating fuse, key and plug of test load into one of sockets. Test load is adjusted to current exceeding setting of tested apparatus. EFFECT: simplified approach to testing of equipment. 1 dwg
