Why Choose the Lovato RFN383200 Thermal Overload Relay?
The Lovato RFN383200 is a reliable thermal overload relay designed to protect three-phase motors against sustained overload conditions in industrial motor control systems. As part of the Lovato RFN38 thermal overload relay series, it combines adjustable thermal protection with a manual reset configuration for controlled restarting following an overload trip.
The RFN383200 features a three-pole design and a Class 10A tripping characteristic for dependable motor overload protection. It also incorporates one normally open and one normally closed auxiliary contact, allowing the relay to interface with contactor control, signalling and fault indication circuits within industrial machinery and electrical panels.
With an adjustable operational current range of 24–32 A, the RFN383200 is designed for motors operating within this current range. It is intended for use with Lovato BF09–BF38 contactors and provides non-phase-failure-sensitive operation for applications where this characteristic is specified.
