RKE Miniature General Purpose Relay

Features

The RKE series 2-pole 7A or 4-pole 5A general purpose power relays are a compact, easy-to-use and cost-effective solution for a variety of switching applications. It is available in both AC and DC versions, with a non-polar LED integrated in the relay and a lockable test button with inspection window. The coil identification can be easily determined by testing the button color (AC red/DC blue), which makes the installation more convenient.
