Product Positioning

The 3RV2031-4XA10 is a standard S2 frame motor protection circuit breaker with an overload range of 49...59A. It features Class 10 tripping characteristics, has no built-in auxiliary contacts, and is suitable for basic overload and short-circuit protection in general motor circuits.

Core Product Advantages and Features
Overload current adjustable from 49 to 59A
The knob sets the overload trip current, corresponding to a motor rated current of 49 to 59 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 845A
When a short circuit occurs, the 845A can trip instantaneously, quickly cutting off the faulty circuit.
Screw terminal wiring design
It uses standard screw terminals, making installation and future maintenance and replacement relatively simple.
