Standard Requirements for Thermal Relay Protection Selection
IEC 60255-149:2013 specifies minimum requirements for thermal protection relays. This standard includes specification of the protection function, measurement characteristics and test methodologies. The object is to establish a common and reproducible reference for evaluating dependent time relays. Thermal overload relays are essential protection devices used to prevent motor damage caused by overheating, phase failure, or prolonged overcurrent conditions. Motor protection schemes should cause minimum process downtime while providing. Protection of the motor and the other branch-circuit components from higher currents, due to short circuits or grounds, is a function of the branch-circuit fuses, circuit breakers, or motor short-circuit protectors. Electrical motors make up a large percentage of power system loads.
