RF915 Lovato RF9 overload relay BG mini contactors 9-15 amp 5.5 kw

Why Choose the 11RF915?

Lovato 11RF915 is a three-pole Thermal Overload Relay designed for reliable motor protection. Phase failure/single‑phase sensitive and manually resettable, it covers 9…15 A operational current and mounts directly on BG06, BG09 and BG12 mini-contactors. With IP20 frontal protection and robust construction, this compact unit suits tight panels while helping safeguard three-phase motors from overload conditions.

Engineered for demanding environments, the Lovato thermal overload relay offers a rated insulation voltage of 690 V and 8 kV impulse withstand. It conforms to IEC/EN 60947-1 and 60947-4-1, plus UL508 and CSA C22.2 n° 14. Operating from -20 to 55 °C up to 3000 m, and with pollution degree 3, it integrates cleanly into BG series motor starters.
