Thermal Overload Relay Setting Formula at Hunter Langham blog

Thermal Overload Relay Setting Formula. Calculate size of each part of dol motor starter for the system voltage 415v, 5hp three phase house hold application induction motor, code a, motor efficiency 80%, motor rpm 750, power factor 0.8 and overload relay of starter is put before motor. Procedure for calculating the trip current rating. This relay uses a bimetallic strip that heats up and bends when current is too high, breaking the circuit to stop the motor. The default ir pickup setting value is 0.4 x in (minimum dial value). Ib = anticipated operating current of the circuit. This curve shows how long a motor can run at different overload levels without damage, helping to set protection limits. Since the relay should ideally be matched to the protected motor and be capable of close sustained overload. Thermal overload calculation [siemens] the above is the formula for thermal overload. 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. Basically to setting the overload value,we refer to this formula : Use the selection table for the specific controller involved. The overload or thermal protection. 1) ib ≤ in ≤ iz.
