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

Instrument transformers are used to step-down current or voltage to measurable values.

Specialty or proprietary products and accessories related to safety sensors and switches.

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

High voltage relays are used to transfer power for high voltage and high frequency applications.

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

Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts
