Why Choose the Lovato 11RFN9033 Thermal Overload Relay?
The Lovato 11RFN9033 is a compact and reliable thermal motor protection relay designed for three-phase motor circuits requiring adjustable overload protection. As part of the Lovato 11RFN9 motor protection relay series, it features a three-pole thermal release, manual resetting and direct mounting on compatible Lovato BG mini-contactors.
The 11RFN9033 combines a Class 10A tripping characteristic with phase failure detection, an integrated test button and a trip indicator. Its direct-mounting design simplifies the construction of compact motor starters, while screw-and-washer terminals provide secure electrical connections for industrial control-panel applications.
With an adjustable operational current range of 0.2–0.33 A and a rated operational voltage of 690 V, the 11RFN9033 is designed for low-current motor protection applications. The relay mounts directly on Lovato BG06, BG09 and BG12 mini-contactors and provides IP20 frontal protection.
