Working principle of AC Relay depends on the theory of solid state relay. Featured with multi pin based terminal and sealed structure, this electrical product can endure high contact load. It starts functioning when external voltage is applied. Its small control signal is used to manage large load of voltage. In built sensor of this relay starts to respond when input signal is applied. Advanced coupling mechanism of this relay activates electrical switch sans using any mechanical component. Accurate diameter and long working life are its main features. We are a prestigious trader and supplier of best grade AC Relay.
