RKL Miniature Power Relay

Features

The RKL Miniature Power Relay is a compact, versatile and easy-to-use relay ideal for any number of applications. With its 16 amp capacity for one pole and 10 amp capacity for 2, 3, and 4 poles, the RKL relay can handle a variety of tasks. In addition, non-polar LEDs integrated into the relay allow for more flexible wiring, and the lockable test button and inspection window allow the user to quickly and easily identify the coil.
