• Name: JSK4-d Range Air Time-Delay Contactor Way Relay

        1. APPLICATION
        JSK4-d range air time-delay contactor relay is used in 50Hz(or 60Hz)、rated voltage up to 380V or DC voltage up to 220V automatic control circuit, for time-delay components, and making or breaking circuit in forecast time
        ■  structure feature
        △  Relay is the modular structure; JSK4-d is arranged by JZC3-22d contactor way relay and SK4-d range air time-delay terminal.  JSK4 is arranged by JZC3-22 contactor way relay and SK4 range air time-delay terminal, all accord air damping theory, use powder metallurgy unit as air filters, regulate knobs, and then continuously change time-delay value.
