WEG RW27-2D3-U023 is a three-pole thermal overload relay from the RW27 series, providing adjustable motor protection from 15.0 to 23 amps. This Class 10 device features manual or automatic reset options and is designed for use with WEG contactors in motor starter applications. It offers reliable protection against phase loss, overload, and locked rotor conditions, ensuring the safety and longevity of three-phase induction motors in industrial control panels.

The RW overload relays protect loads against overheating caused by overloads or phase loss. When we have an overload or a phase loss in the circuit, the motor current increases. Such current rise activates the tripping mechanism that will actuate on the auxiliary contacts 95-96 (NC) and 97-98 (NO). The auxiliary contacts disconnect the load by means of a contator. The time for disconnection is related to the overload current and the current set on the relay, which is properly represented on the relay tripping curve. After the trip, it is necessary to wait for the system to reestablish in order to do the reset, which can be done automatic or manually.
