Smart Multifunction Monitoring Relays
Remotely control these relays through an app on your smartphone—they simultaneously monitor phase, voltage, and frequency. The downloadable app lets you change the tripping range, modify settings, and save programs to apply to multiple relays. Tap your smartphone or tablet to the relays to connect to them. They use NFC (near field communication), so you don’t need to manually pair them like Bluetooth devices.
You’ll often see these relays used to protect motors, generators, and other three-phase circuits from burning out or overheating. They'll switch the circuit off if they detect voltage or frequencies outside of the set range or phase loss, imbalance, or reversal. You can see that they're wired correctly and when they're actuated based on the LED indicators. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

Motor Starters
Provide on/off control for a motor and protect it from overloads. These starters shut off the motor if current exceeds the full-load current rating. All have an adjustable overload relay that allows you to set the exact overload current you need.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
Starters with auxiliary contacts can send a signal or connect to another device, such as an alarm or indicating light.
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

Low-Profile Motor Starters
With a shallower depth than most other starters, these fit in narrow spaces. They provide on/off control for a motor and protect it from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).

Enclosed Reversing Motor Starters
Rated NEMA 4X, these enclosed starters are protected from corrosion and washdowns. Use them with motors that run forward and backward, such as motors for conveyor belts. They provide on/off control and protect motors from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light. Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
Add auxiliary contact blocks to signal more devices.

Heavy Duty Motor Starters
Sealed coils protect these switches against moisture, heat, dirt, and mechanical and thermal stress. They have a solid state overload relay that extends motor life in demanding applications and protects it from overloads—starters will shut the motor off if current exceeds the full-load current rating. The relay is adjustable; set it for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light. Also known as NEMA starters.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
NEMA contact sizes 0 and 1 are universal mount and fit Cutler-Hammer, GE, and Square D installations.
