J7KNU (-AR)

J7KNU Micro Motor Contactor/Relay Datasheet

Features

Relay-size contactor, smallest in the world!

AC and DC operated
Integrated auxiliary contact
Available as motor contactor and contactor relay
>3 mm contact clearance acc. to IEC 60335-1 for safety applications
Reversing contactor with mechanical interlock
Mirror contacts (NC) acc. to IEC 60947-4-1 for safety applications
J7KNU is designed to fit 15 mm DIN rails, but J75KN snap-on adapter make it suitable also for the standard 35 mm DIN rail

Probably the smallest contactor of this type.

J7MN compared to J7KNU.
