RF200150 - T/O RELAY RF200 90-150A

Why Choose the RF200150?

The Lovato RF200150 is a three‑pole thermal overload relay engineered for dependable motor protection. Phase failure and single‑phase sensitive, it protects three‑phase loads across 90–150 A and suits demanding industrial environments. With manual or automatic reset options and screw mounting, it integrates seamlessly with Lovato B series contactors for straightforward panel assembly, helping you build robust, compliant control solutions with minimal downtime.

Designed to meet IEC/EN 60947-1 and 60947-4-1, and recognised under UL508 and CSA C22.2 n° 14, this relay delivers solid electrical endurance with Ui 1000 V and Uimp 6 kV. An IP20 frontal degree and Pollution degree 3 support panel integration, while an operating range of -25 to 60 °C and altitude up to 3000 m ensure reliable performance in varied site conditions.
