Description
The ABB RT1P Thermal Overload Relay is a motor protection device designed for compatible ABB C-2000 IEC contactors and starters. Featuring an adjustable current range of 10 to 16 A, it helps protect motors against overload conditions by detecting excessive current and initiating a trip through the connected contactor control circuit.
Designed for industrial motor control applications, the RT1P supports Type 2 coordination when used with compatible C-2000 starters and the specified Class J fuse protection. This coordination helps ensure that, under short-circuit conditions, the starter assembly presents no danger to personnel or the installation and remains suitable for further use, subject to the manufacturer’s requirements.
The RT1P features a thermal overload protection mechanism with a Class 10 trip characteristic. Its contactor-mounted design and selectable manual or automatic reset options support integration into compatible motor starter assemblies, helping provide dependable motor protection in industrial equipment and electrical control panels.
