Product Positioning

The 3RV2031-4WA16 belongs to the S2 frame model with an overload range of 42...52A. It adopts the Class 10 standard tripping characteristics and can provide overload and short circuit protection for motors with normal start-up time.

Core Product Advantages and Features
Overload current adjustable from 42 to 52A
The rotary overload current setting corresponds to a motor rated current range of 42 to 52 amps.
Class 10 standard escape characteristics
Suitable for motor loads during normal start-up times, providing stable and reliable overload protection.
Transient short circuit trips 741A
When a short circuit occurs, the 741A trips instantaneously, quickly cutting off the faulty circuit and protecting the motor and wiring.
S2 Frame Standardized Design
It shares the same external dimensions and installation method with other models in the same series, which is conducive to the unified planning of the distribution panel.
