Thermal Overload Protection for Motor Control Systems
Thermal overload relays protect motors by responding to sustained overcurrent conditions that can cause excessive heating. Selecting a relay with an appropriate adjustable current range allows the protection setting to be matched to the operating requirements of the connected motor.
The Lovato 11RFNA92V3 combines a 1.4–2.3 A adjustable current range with Class 10A tripping, automatic resetting and phase failure detection. Direct mounting on compatible BG06, BG09 and BG12 mini-contactors enables compact motor starter assemblies for industrial machinery and electrical control panels.
Typical Applications
- Thermal overload protection for compatible electric motors.
- 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.
