Selecting the correct relay is critical to the reliability of the controller and the integrity of the switched signal. Affordable Housing $99 Move in Special $ 1BR at $670 1 BR | 1 BA . the above are examples where relays are (probably) the best choice. One main difference between them is electromechanical relays have moving parts, whereas solid-state relays have no moving parts. Wiki User. 13 An IDMT type over current relay is used to protect a feeder through 500/1A CT. A solid-state relay is costlier than electromechanical relays due to the use of semiconductors. Electricity and Controls for HVAC-R - Page 270 an "internal" fault) is capable of forcing the two CTs currents to become unequal.
