1. The thermal relays also provide temperature compensation, action indication, automatic and manual reset, stop, and testing functions. The products are characterized by stable and reliable performance. The thermal relays can be plugged into contactors or installed indepe-ndently.Compliant standards: IEC/EN 60947-4-1, IEC/EN 60947-5-1.
