The Lovato 11RF9033 is a three-pole thermal motor protection relay designed to protect three-phase motors against overload and phase-failure conditions. Its adjustable operational current range of 0.2–0.33 A enables accurate protection of low-current motor circuits.
This phase-failure-sensitive relay features manual resetting, tripping class 10A, a test button and a visible trip indicator. One normally open and one normally closed auxiliary contact are included for signalling and integration with control circuits.
The 11RF9033 mounts directly onto Lovato BG06, BG09 and BG12 mini-contactors, supporting compact motor starter assemblies. Its 690 V rated operational voltage, IP20 frontal protection and broad operating-frequency range make it suitable for industrial control panels and machinery.
Thermal motor protection relays monitor the current supplied to a motor and trip when a sustained overload creates a potentially damaging condition. Phase-failure sensitivity adds protection when one phase is lost, helping reduce the risk of motor overheating and premature equipment failure.
The Lovato 11RF9033 combines an adjustable current setting with manual reset, auxiliary signalling contacts and direct contactor mounting. These features support compact, coordinated motor starter assemblies that are straightforward to test, monitor and maintain.
