JSK4-D Range Air Time

JSK4-D Range Air Time

JSK4-D range air time delay contactor relay is designed to make or break an electrical circuit based on preset time. It comes with modular structure, and is mainly made up of a JZC3-22d contactor relay and SK4-d air time delay terminals. The electrical apparatus works based on air damping theory, and uses powder metallurgy strip as the air filter. It is capable of continuous adjustment of the delayed time.
