Overload Relay Trip-Current Setting at Ben Birtwistle blog

Overload Relay Trip-Current Setting. Per nec, an overload must ultimately trip at 125% of fla current (heater) setting for a 1.15 service factor motor, and 115% fla for a 1.0 service. In compliance with international and national standards, the setting current is the rated current of the motor and not the tripping current (no. Use the selection table for the specific controller involved. 1) check your overload relay condition.perform test trip to ensure it is function properly,if not change it. The default ir pickup setting value is 0.4 x in (minimum dial value). Because of the variable voltages around the world, motors for pumps are made to be used at both 50 hz and 60 hz in a wide voltage range. 2) check your full load ampere. Since the relay should ideally be matched to the protected motor and be capable of close sustained overload protection, a wide range of relay adjustment is desirable.
