RF95 Lovato RF9 overload relay BG mini contactors 3-5 amp 1.5 kw

Why Choose the 11RF95?

Designed for dependable motor protection, the Lovato 11RF95 thermal overload relay delivers phase failure and single‑phase sensitivity across a 3…5 A setting range. This three‑pole, manual‑reset unit mounts directly on BG06, BG09 and BG12 mini‑contactors for compact installation. With a frontal IP20 rating and a 10 A Ith, the SKU 11RF95 helps safeguard three‑phase motors while enabling quick, controlled resetting after an overload trip.

Built to international standards, it conforms to IEC/EN 60947‑1 and 60947‑4‑1, plus UL508 and CSA C22.2 n° 14. It offers 690 V Ui, 8 kV impulse withstand, and reliable performance from −20 to 55 °C up to 3000 m altitude. Pollution degree 3 construction and 2.3 Nm terminal torque support robust connections, while its 116 g build aids straightforward panel assembly and service.
