2, control voltage: 3TF AC and DC operations, 3TB only AC operation.
3. Insulation voltage: the same capacity 3TF contactor is AC690V, and 3TB is AC660V.
4, mechanical life and electrical life: the same capacity 3TF mechanical life and electrical life are higher than 3TB.
5, auxiliary contacts: 3TF can be added to the auxiliary contact block, 3TB can not. 3TB is slightly inferior to 3TF in performance, but its price is also low. If the application requirements are not very high, 3TB is enough.
