    These relays handle the high starting (inrush) currents that often occur when turning on a vehicle. Also known as ISO relays, their blade terminals meet ISO 8092-1 dimensional standards to fit in road vehicles for easy maintenance and repair.
    Relays with surge suppression coverage prevent damage to sensitive equipment by reducing the 300V to 500V spike that happens when you switch relays off.
    Surface Mount—Relays for surface mounting have a tab for added security in high-vibration applications.
    Partial—Relays with partial surge suppression coverage bring this spike down to 100V.

    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.

    Operate equipment that cycles on and off from your control cabinet. Often called definite-purpose contactors, these relays meet UL 508 for use with air conditioning and heating. Mount them directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They have recessed terminals that prevent fingers and other objects from touching live circuits. You can wire the control circuit on either side of the relay, which helps you use less wire.
