Contactor safety 2NO-2NC 3-pole 30HP 37A 120V

Safety contactors provide mechanically linked positively guided contacts, required in feedback circuits of modern safety applications. The mechanically linked NC auxiliary contacts will not change state when a power pole welds. In addition, the gold-plated bifurcated auxiliary contacts are ideally suited for low-energy applications or feedback control circuits with multiple series-connected NC auxiliary contacts. Mechanically linked NC auxiliary contacts. Front-mounted auxiliary contacts: gold bifurcated permanently fixed protective cover to prevent manual operation red contact housing for easy identification incorporates IEC 60947-5-1 mechanically linked or IEC 60947-4-1 mirror contact symbol.
