lovato sm1x1220 sm1 auxillary contacts side mount 2no

Why Choose the SM1X1220?

Designed for seamless integration with Lovato SM1P and SM1R devices, the SM1X1220 is an add‑on auxiliary contacts accessory that side‑mounts to expand 2NO signalling. With a robust 690 V Ui and 4 kV Uimp, it delivers reliable performance for control and indication needs. This compact module helps extend functionality without redesigning panels, maintaining compatibility within the SM1X family.

Built for endurance, the unit is rated for 100000 mechanical cycles and operates from -20 to +60 °C, with storage down to -50 °C. Terminal connections tighten to 1 Nm for secure wiring, and performance is verified up to 3000 m altitude. Conformity includes IEC/EN 60947-1 and 60947-5-1, plus UL508 and CSA C22.2 n° 14.
