    Relay

    Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
    Integrated Heat Sink—Relays with an integrated heat sink disperse heat to increase the relay’s current rating.

    For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Connections are accessible from the front, so you can mount relays side-by-side. Also known as definite-purpose contactors.
    Auxiliary contacts for 3.8"-7.2" Ht. relays are also available. They allow you to add a signaling device or control another relay. Please select 6564K99, then select the McMaster-Carr part number of your relay and whether you want to switch one circuit on or off.

    Energy-Saving Motor Starters

    Image of Product. Front orientation. Motor Starters. Energy-Saving Motor Starters.
    Save electricity and extend motor life by reducing the motor's starting current. These starters gradually start and stop motors. Use them on motors where torque varies, such as pumps, compressors, and conveyors. All have an auxiliary contact to send a signal or connect to another device, such as an alarm or indicating light.
