Electromagnetic contactors KNE U, KNI series

ТУ16-94-БКЖИ.644131.001ТУ, ТУ16-94-ИБМШ.644131.005ТУ

KNE U contactors are monostable self-resetting electromagnetic devices with DC control circuits.

KNI contactors are bistable polarized electromagnetic switching devices. They are operated by square voltage pulses with duration of not less than 0,3s.

Contactors are intended for switching of  DC circuits up to 132 V and AC circuits up to 418 V, frequency from 50 to 1000 Hz and can be used in critical devices of mobile and fixed installations: in military equipment, shipbuilding, aviation and space equipment, on NPPs, etc.
