DRAW-OUT EXECUTION
All N series contactors can be supplied in a withdrawable execution. This execution allows the three positions - <<Service>>, <<Test>>, and <<Out of Service>>, with mechanical and electrical indication.
The connection of the main poles is made by spring clamps safely designed, that take into account the thermal effects as well as the electrodynamic stresses imposed. The control circuit and the auxiliary contacts are connected through brush contacts that move together with the main poles.
If neccessary, additional contacts can be connected to plug-in contacts, so that when the contactor is in the <<Out of Service>> position, all servicing or the substitution of the complete contactor, can be made without disconnecting the main and auxiliary wiring.
