The CM-KRN relay is from the CM contact protection relay range. This protection relay operates with a rated control supply voltage of 110-130 V AC, has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A and works according to the open-circuit principle. It acts as two-position switch and protects and reduces load from sensitive control contacts. It can be used with or without latching function. The bounce time of control contacts can be bypassed by the adjustable response delay time (0.05-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory.
