WEG RW27-1D2-D004 RW27 series thermal overload relay with 0.28-0.4 A adjustable current range. Provides Class 10 trip protection against overloads and phase loss. Includes one normally open and one normally closed auxiliary contact for control signaling. Designed for direct mounting on CWM9-40 contactors. Manual or automatic reset operation.

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.
