lovato sm1x1120 sm1 auxillary contacts front mount 2no

Why Choose the SM1X1120?

The Lovato SM1X1120 is a front‑mount 2NO auxiliary contact accessory designed for seamless integration with SM1P and SM1R devices. As part of the SM1X family, this add‑on contact expands signalling and control options without altering the main protection setup. With the SKU SM1X1120, installers gain a lightweight 16 g module that maintains robust performance and meets recognised international standards for industrial control applications.

Engineered for reliability, the unit offers Ui 300 V and Uimp 4 kV insulation performance, a mechanical life of 100000 cycles, and secure terminations at 1 to 1 Nm tightening torque. It operates from -20 to +60 °C and stores between -50 and +80 °C, with installation permitted up to 3000 m altitude. Conformity includes IEC/EN 60947-1, IEC/EN 60947-5-1, UL508 and CSA C22.2 n° 14.
