Abstract (en)
[origin: EP0275750A1] The interrupter comprises a control mechanism with handle and differential release (46) comprising a totalising transformer and a release relay (98) cooperating by means of a release rod (142) with the main lock of the mechanism, and with a signalling lock (158) of a fault-indicating lever (152). Automatic resetting of the relay (98) is performed with a resetting lever (144) mounted with limited swivel on the spindle (146) of the indicator lever (152). A projection of the plate for driving the moving contacts causes, during the closing travel of the handle, the displacement of the resetting lever (144) to a neutral position, and the passage of the indicating lever (152) to a passive position. Applications: range of differential interrupters from 25 A to 63 A, and with sensitivities from 10 mA to 500 mA. <IMAGE>
