Overview
Our 220v Ac Relay is used in various circuit protection and automatic control devices to increase the number of output points. It has the advantages of convenient installation, good stability, low power consumption, high precision and small error. It adopts precision imported Omron chip, which is safe and stable. It is silent, noiseless and anti-interference. Protect the safety of the equipment, work stably, and the action instructions are clear.
Our 220v Ac Relay adopts fast terminal design, easy wiring, one plug and tighten, excellent conductivity alloy terminal. Guide rail type buckle, light structure, one card is good and easy to install. Strict quality detail monitoring, better than ordinary materials, safer and long service life. It has instantaneous action characteristics and is used for overload and short-circuit protection of generators, transformers and transmission lines as starting elements.
