SBW series thermal overload relay is mainly designed for 3-phase motor to control and protect the electric appliances connected in parallel. It has 2 contacts on the bimetal, corresponding to the 2 static contacts on the base. When the temperature reaches to the prescribed point, the bimetal components move swiftly to separate the 2 sets of contacts and cut the circuit off. Then it will move again to open the circuit after the temperature drops to the normal range.
1. Capacity of contact: 12A/380VAC 10A/440VAC
2. Opening temperature: 80-160℃, in increment of 5℃; tolerance of opening temperature: ±5℃
