The Alternating Relays Are Used to Alternate the Use of 2 Motor Circuits. When the Coil is Energized the First Time, One Contact Closes and Will Open When the Coil is De-Energized. When the Coil is Energized Again the Other Contact Will Close and Will Open When the Coil is De-Energized. The Contacts From the Alternators Are to Be Used In the Control Circuit of Starters That Control Pumps or Compressor Motors.
- Can Be Wired In A Control Panel or As a Separate Unit
- NEMA A600 Rated Fixed Contacts
- UL Listed, CSA and CE Certified
- SPST Contacts
- Compact Design 45mm Wide
- Can Be Mounted on 35mm DIN 3 Track or Direct Panel Mount

*** When Selecting the Alternating Relay Choose the Model Number Closest to Your Operating Voltage.
Coils Can Operate Within a 15% Range. Do Not Exceed Your Operating Voltage As the Life of the Coil Will Be Shortened.
