Product Positioning

The 3RV2031-4WB10 is a standard S2 frame model with an overload range of 42...52A. It adopts a Class 20 tripping design and has no built-in auxiliary contacts. It is suitable for motor circuits with long start-up times and only basic protection functions.

Core Product Advantages and Features
Class 20 Long Jump Characteristics
It has a longer break-out time than Class 10, making it suitable for loads with longer start-up times and higher start-up currents.
Overload current adjustable from 42 to 52A
The rotary overload current setting corresponds to a motor rated current range of 42 to 52 amps.
The wire can be connected to 1...50mm²
The terminals can be connected to single-core 1...50mm² or double-core 1...35mm² wires, providing excellent wiring flexibility.
IP20 protection rating
Provides basic electric shock protection and is suitable for installation in general distribution boxes.
