In an interrupter with a resistor insertion system, the resistor insertion system comprises two auxiliary contacts, a first of which is electrically connected to a semi-mobile permanent current contact and the second of which is electrically connected to a fixed arc contact. The two auxiliary contacts are mounted to be mobile relative to each other along a longitudinal axis so as to be able to move toward each other when the interrupter closes to make a connection that short-circuits the resistor and so as to be constrained to move together along the longitudinal axis when the interrupter closes before making the connection which short-circuits the resistor, to increase the resistor insertion time.
