Relay

For electrical control systems and automation equipment, relays are among the most essential components for switching, protection, and signal control functions. Relays enable low-power control circuits to safely switch higher-power loads, provide electrical isolation, and allow automated control of motors, lighting, and industrial processes. Electrical.com carries an extensive selection of relays from all major manufacturers, including new, used, surplus, and re-certified options. These components are designed to meet the diverse needs of industrial automation, motor control systems, building management, and process control applications.
