BIMETALLIC OVERLOAD RELAYS ATC Diversified’s Overload Relays provide thermal Trip Class 10 overload protection for single and three phase motors, and phase loss protection for three phase motors. Other features like IP20 guarded terminals with dual terminal markings, integral stop button, and direct mounting will help you reduce your total installed costs and enhance the features and performance of your equipment. Proven Our Overload Relays are UL Listed and CE marked meeting global standards requirements. Reliability Trip Class 10 for reliable and accurate protection against overload conditions. Trips within 10 seconds when carrying a current of 720%. Trip Indication Visible trip indication to provide clear indication of what device tripped, simplifies troubleshooting in panels. Visible Markings High visibility labels and markings; dual IEC and NEMA terminal markings for ease of wiring anywhere in the world. Modular Design Modular design allows our Overload Relays to be direct mounted onto CON Series Contactors. Visible Certifications Our product certifications and electrical ratings are clearly marked on the outside of the devices for easy reference during installation. Added Safety IP20 guarded terminals with dual terminal markings prevent accidental contact with live parts. MUL TIPLE FUNCTION ADVANTAGES High Fault SCCR

  • High fault short circuit current rating of 100kA @ 480V and 600V with Class J fuses, provides safety and reliability in high fault applications. Adjustable Current Setting
  • Full load current adjustment ratio of approximately 1:1.5 enables overload relay to be set to exact FLA of motor. Phase Loss Sensitivity
  • Single phase sensitivity to protect motors against damaging phase loss conditions. Selectable Reset Mode
  • Manual or automatic reset and test modes, and stop button all in a single device for convenient control circuit wiring. Seamless Compatibility
  • Overload Relays direct mount onto all CON Series Contactors. Trip Test Function
  • Trip test function standard on all overload relays allows for easier installation, testing, and troubleshooting.
