Relays are electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit.
Relays and Relay Accessories Categories
Aerospace Contactors (12 suppliers)
Aerospace contactors are high-performance, high-capacity, circuit controls designed for aerospace applications.
Electrical Contactors (173 suppliers)
Electrical contactors are used to switch high power in power circuits. Unlike relays, these electrical devices are normally connected directly to the load or current-carrying circuit.
Electromechanical Relays (704 suppliers)
Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.
High Voltage Relays (103 suppliers)
High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life.
Motor Contactors (270 suppliers)
Motor contactors are relays with large current capacity for connecting and disconnecting a motor from the power supply. Typically, motor contractors are multi-pole for control of all current carrying conductors.
Motor Starters and Contactors (592 suppliers)
Motor starters and contactors are motor-starting devices. They combine a contactor with overload protection and are designed for starting AC or DC motors.
Protective Relays and Monitoring Relays (332 suppliers)
Protective relays and monitoring relays detect or monitor for abnormal power system conditions.
Reed Relays (113 suppliers)
Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors.
Relay Sockets (161 suppliers)
Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit.
Safety Relays (169 suppliers)
Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts.
Solid State Relays (606 suppliers)
Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications.
Thermal Overload Relays (161 suppliers)
Overload relays prevent an electric motor from drawing too much current and overheating; includes thermal and solid state overload types.
Time Delay Relays (253 suppliers)
Time delay relays and solid state timers use solid state electronic devices to provide a time delay.
