    DIN-Rail Mount

    Relay-Socket Mount

    Prevent changes in frequency from damaging sensitive equipment. Often used with motors, fluorescent lighting, and controllers, these relays cut power to your device if the frequency falls outside the set range. Switches on the front of these relays let you set your trip frequency and time. You can see that they're wired correctly and when they're actuated based on the LED indicators. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits.
    DIN-Rail Mount—DIN-rail mount relays snap onto 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
    Relay-Socket Mount—Relay-socket mount relays plug into a socket (sold separately), which is required for installation.
