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.

Key Advantages

  • Compact thermal motor protection relay for three-phase applications.
  • 0.2–0.33 A adjustable operational current range for precise overload settings.
  • Class 10A tripping characteristic for motor overload protection.
  • Manual reset provides controlled resetting following a trip.
  • Integrated phase failure detection, test button and trip indicator.
  • Direct mounting on Lovato BG06, BG09 and BG12 mini-contactors.

  • Integrated test button and trip indicator.
  • Direct mounting on BG06, BG09 and BG12 mini-contactors.

Reliable Motor Protection for Industrial Machinery

Thermal motor protection relays such as the Lovato 11RFN9033 respond to sustained overcurrent conditions that can cause excessive motor heating. Its adjustable current setting allows the relay to be configured within the specified 0.2–0.33 A range, while the Class 10A tripping characteristic provides defined overload response behaviour.

The 11RFN9033 also incorporates phase failure detection, a test button and a trip indicator to support motor protection and maintenance. Direct mounting on compatible Lovato BG mini-contactors allows the relay and contactor to form a compact motor starter assembly for machinery and industrial control systems.

Typical Applications

  • Low-current three-phase motor protection.
  • Industrial machinery and automation equipment.
  • Compact motor starter assemblies.
  • Electrical control panels.
  • OEM machinery and production equipment.
  • Motor circuits using Lovato BG06, BG09 or BG12 mini-contactors.
