RTO Relay
Overview

RTO Thermal Overload Relays complement the MO range of contactors and can be directly mounted onto them. The relays are compensated for ambient temperature and are sensitive to phase failure. They feature front access to START and STOP/RESET buttons and are equipped with three contacts for Alarm, Trip, and Start functions. 

RTO Relay Benefits

Benefits

  • Direct mounting on MO contactors simplifies installation. 
  • Visual status indication (tripped/non-tripped) visible from the front enhances monitoring. 
  • Front access to terminals for easy wiring streamlines installation. 
  • Separate mounting facility available for flexibility. 
  • Auto/manual reset function offers versatile reset options
