Surplus New And Used Relays And Relay Accessories

Relays are electromechanical switches in which the change in current in one electric circuit controls the flow of electricity in another circuit. You can further refine your specific search using the category(ies) below:

Auxiliary Contacts

Auxiliary contacts are secondary switching devices which work in conjunction with primary switching equipment such as circuit breakers, relays, and contactors.

Electromechanical Relays

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.

Ground Fault Relays

Ground fault relays protect electrical equipment from ground fault.

Motor Starters & Contactors

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 & Monitoring Relays

Protective relays and monitoring relays detect or monitor for abnormal power system conditions.

Relay Sockets

Relay sockets are devices that accept relays.

Safety Relays

Safety relays have force-guided (positive-driven) contacts and have three relays.

Solid State Relays

Solid state relays are semiconductor devices that can be used in place of mechanical relays.

Thermal Overload Relays

Thermal overload relays provide overcurent protection for motors.

Time Delay Relays

Time delay relays and solid state timers use solid state electronic devices to provide a time delay.
