Nettet13. feb. 2013 · Motors rated more than 1 hp, used in a continuous-duty application without integral thermal protection, must have an overload device sized to open at no more than 115% of the motor nameplate FLC rating [430.32(A)(1)]. NettetThe thermal time constant of most types of motors is of the order of 15 to 20 minutes, hence for protection from overloads the relay should have a time constant slightly lower than this. When a motor stalls, a current equal to the starting current flows and serious damage results if it persists for a time longer than the starting time. snow curls
