Why Choose the Lovato RF200200 Motor Protection Relay?
The Lovato RF200200 is a robust three-pole thermal overload relay designed to provide motor overload protection in three-phase industrial applications. Part of the Lovato RF200 motor protection relay range, it offers an adjustable operational current range of 120–200 A and is suitable for use with Lovato B series contactors.
The RF200200 uses thermal overload release technology and features manual or automatic resetting, allowing the reset method to be selected according to the application. A built-in test button and trip indicator support commissioning, testing and fault identification, while the relay's Class 10A tripping characteristic is designed for motor protection applications.
With a rated operational voltage of 690 V, a rated insulation voltage of 1000 V and an operating frequency range of 50–60 Hz, the RF200200 is engineered for demanding industrial motor control systems. Its screw fixing arrangement and integrated auxiliary contacts support installation and control circuit integration.

Reliable Thermal Overload Protection for Industrial Motors
Thermal overload relays help protect electric motors against damaging overload conditions by responding to excessive current over time. The Lovato RF200200 provides an adjustable 120–200 A operating range and Class 10A tripping characteristic for high-current three-phase motor applications.
Manual or automatic reset selection allows the relay to be configured for different operating requirements, while its auxiliary contacts can be incorporated into control circuits to interrupt contactor operation or provide status signalling when the relay trips.
Typical Applications
- Three-phase industrial motor protection.
- Motor starters and motor control centres.
- Industrial machinery and production equipment.
- Pumps, fans and material handling systems.
- Electrical control panels and switchgear.
- Industrial automation and motor control systems.
