TEST DEVICE FOR A DIFFERENTIAL PROTECTIVE ELECTRICAL APPARATUS INCORPORATING THIS DEVICE, IN PARTICULAR FOR A DIFFERENTIAL CIRCUIT BREAKER

摘要

The test assembly is characterized in that it comprises a conductive strip 30 having two elastic branches 31, 32, the first 31 normally in contact with a fixed contact 34 connected to the main circuit, the second 32 normally distant from a contact fixed 12 of the calibrated test resistance, the first branch 31 being arranged in the course of a mechanism element 36 and the second being capable of being pushed back by a push button 18 towards said contact 12 connected to the test resistance .
