11BGX1031 Lovato contactor auxiliary contacts screw terminal 3no+1nc

Why Choose the 11BGX1031?

Optimise your BG… series mini-contactors with the Lovato 11BGX1031 auxiliary contact accessory. This 4‑pole unit provides a 3NO+1NC configuration with mirror and mechanically linked contact function for dependable status signalling and interlocking. Designed for front‑centre mounting with screw terminals, it integrates quickly into control panels while maintaining robust performance under demanding conditions.

Built to international standards, the 11BGX1031 achieves Ui 690 V, Uimp 6 kV and Ith 10 A for reliable insulation and thermal capacity. It operates from −50 to +70 °C, stores to −60 to +80 °C, and is rated to 3000 m altitude. Compliant with IEC/EN 60947 and UL/CSA equivalents, this compact 28 g accessory tightens to 0.8–1 Nm, ensuring secure terminations and long‑term service.
