Nominal Coil Voltage @ 60Hz

This is the nominal input/control voltage required to fully energize the device to open or close its power contacts. If a greater voltage is applied than the nominal voltage it can damage the coil and contacts within the device, making it operate less efficiently or stop working altogether. The device will chatter if the voltage coil input is below the designed voltage. Values with dashes (e.g., 20-28V) identify that a device can operate within the voltage range. Values with slashes (e.g., 120/240V) indicate that the device is dual voltage and can operate with either value shown. Some devices are only compatible with alternating current (AC) or direct current (DC) circuits. Other devices are compatible with both AC and DC circuits.

Features

Alternating Contacts toggle between two circuits to split the workload and extend the mechanical service life of the contactor. They are commonly used to sequence load matching and distribute equal run times.
Finger Safe have openings that are smaller than 12.5mm and can't be accessed with fingers or similar objects. They protect against accidental contact with live wires, terminals, and clips.
Latching Contacts have latching and unlatching coils that require momentary electrical signals to open and close their circuits. When power is applied to either the latching or unlatching coil, the contactor will switch between energized or de-energized and stay in that state until it receives another control signal. They use less energy than electrically held contactors and operate quieter because they don't require a constant input to the voltage.
Miniature Frame have compact constructions smaller than standard IEC contactors and help save space in tight enclosures and control cabinets.

IEC & NEMA Control Relays

Available25 products

IEC and NEMA control relays are made to standards designated by the International Electrotechnical Commission or the US National Electrical Manufacturers Association. They have multiple configurable (normally open and normally closed) contacts, allowing compatibility with other components when designing control circuits. These relays have robust constructions, provide longer life cycles, and handle higher current loads and voltages than standard control relays.

Brand

Surface-Mounted Relays

These relays have mounting features that secure with screws on surfaces like walls, control panels, and enclosures. They help protect relays from moving due to vibrations and impacts, making them ideal for applications around running motors.
