Thermal Overload Relays (E3RU)

E3RU series thermal relays are suitable for using in the power system with AC50/60Hz, rated operation voltage up to 690-1000V, rated operation current from 0.1A to 100A. They are used to protect AC 3 phase asynchronous motors against overload and phase failure. They also have the factions of temperature compensation and trip indication. The products can be fixed with E3RT series contactors, or be independently fixed. The items conform to IEC60947-4-1.
