Thermal Overload Protection for Three-Phase Motors
Thermal overload relays protect motors by responding to sustained overcurrent conditions that can cause excessive heating. When the current exceeds the configured operating range for sufficient time, the relay trips the associated control circuit to help protect the motor and connected equipment.
The Lovato 11RFNA91 combines an adjustable 0.6–1 A current range with Class 10A tripping and direct mounting on compatible BG mini-contactors. Its automatic reset function, test button and trip indication support practical operation and maintenance within compact motor starter assemblies.
Typical Applications
- Three-phase motor overload protection.
- Motor starters using Lovato BG06, BG09 or BG12 mini-contactors.
- Industrial machinery control panels.
- Compact motor control assemblies.
- OEM automation and machine-building equipment.
- Industrial motor switching and protection systems.
