RL621 is a universal electronic step-by-step relay with bistable relay switching device and equipped with zero crossing technology. The zero crossing switching allows to control higher loads with considerably higher reliability and durability compared to an asynchronous switching. The installation does not require direct connection to the neutral wire. The output to the load is 230V. The device is inserted in a plastic casing and immersed in UL94V-0 flame retardant polyurethane resin. The package leaflet with the user manual is supplied with it.
