Summary:A differential interruptor (10) comprises a switch bar (32) arranged as a contact-holder rotary shaft (30, 26), a transformer- adder associated with a release relay (54) with automatic reset, and an operating mechanism (34) with handle (64) and lock (88). The end (74) of the link-rod (70) situated opposite the axle of articulation (72) of the toggle engages upon the establishment of the mechanical link with a first support stop (76) for the catch lever (78) and a second support stop for the switch bar (32). The relay (54) transmits the release command to the lock (88) via a release lever (98) associated with an intermediate mechanical amplifier. This results in a three-stage mechanism for multiplying down the forces between the relay (54) and the bar (32), this enabling the energy of release to be reduced.
