UNSR thermal relay is suitable for AC 50/60Hz, voltage up to 660V and current up to 630A, generalAC motor of long or discontinuous long operation, used as overload protection and has the functionsof breaking phase protection, temperature compensation, and trip indication. It can automaticallyand manually get back. It can be fixed with contactor UNSC together, also be independtly fixed. Theproduct conforms to IEC60947-4-1 stardand.
