Overview
Our 120v Ac Relay has a beautiful appearance and adopts a high-quality shell with high strength, high temperature resistance, corrosion resistance and good flame retardancy. Silver alloy contact has good conductivity and long service life. Every detail is designed carefully, focusing on quality, making products carefully and using them for a long time. Reliable pull in, which can effectively reduce open circuit and short circuit. Our relays are cost-effective. We have complete models and technical support.
Our 120v Ac Relay adopts high-quality composite silver contacts with strong conductivity and large carrying current. According to customer needs, we can customize the materials suitable for resistive load, inductive load or capacitive load contacts. It has instantaneous action characteristics and is used for overload and short-circuit protection of generators, transformers and transmission lines as starting elements.
