LT4 Mechanical Interlock Contactor

LT4 Mechanical Interlock Contactor
Product Detailed
LC2 mechanical interlock contactors (AC contactor) Operation class: AC-3 Insulation voltage:690V Altiude:up to 2000m

 LT4 Mechanical Interlock Contactor

LT 4-Dxx  series contactors are specially  designed electromagnetic devices for commutation of three phase induction motor with reversing controlling scheme.They represent two alternating current contactors LT 4-Dxx series factory mechanically joined together.The mechanical joining also provides locking of the contactors against simultaneous switching on.The contactor is used for reverse control of induction motors with shortly joined motor. The contactors from the series are offered for consumers up to 95A


switching on of electrical motors in one direcrion of rotation and reversing of the rotation direction at out side commandmaking of control systems remarkable with high reliabillity of current characteristics reliable switching on or separation of power contactssecured part of the contactors against consumer contactsecured cover of the movable part of the contactorimpossibility for simultaneous switching on of the two contactors from the group due to mechanical locking
