Reverse Contactors LT4


Technical characteristics:

– Rated current: 18A/25A/32A/40A/65A/95А
– Operaton class : АС3
– Rated operating voltage of the controlling coil: 230V АC; 50/60Hz
– Rated operating voltage of the power circuit: up to 690V АС
– Insulation voltage: 690V
– Surge voltage wear resistance: ≥8 000V
– Number of contacts: 3 NO power contacts +1NO operating
(for contactors over 40А there is also auxiliary 1NC contact)
– Electrical wear resistance (number of cycles):≥1 000 000
– Mechanical wear resistance (number of cycles):≥10 000 000
– Number of cycles per hour: up to 600 switchings
– Ambient temperature : -10°÷60ºС
– Maximum altitude: 2000m


Mounting: on a DIN rail or using screws to flat surface in a vertical position with maximum incline of ±5°



–  Material: resistant to UV rays, self-extinguishing
– Switching ON of electrical motors in one direction of rotation and turning (reversing) of the rotation direction at outside command.
– No option for simultaneous switching ON of the two contactors in the group due to mechanical interlock
– High reliability of the current parameters
– Secure separation of the power contacts
– Easy mounting
– Long life
– The contactor is used for reverse control of inductive motor with short circuited rotor.
– Developing of control systems
