Product Positioning

The 3RV2031-4XA15 is a model in the 3RV2031 series with an overload range of 49...59A. In addition to having Class 10 standard protection features, it also has 1NO+1NC auxiliary contacts built in, which can directly provide trip status signal feedback.

Core Product Advantages and Features
Built-in 1 NO + 1 NC auxiliary contact
Without the need for additional auxiliary contact modules, the circuit breaker's operating status can be fed back to the PLC or monitoring circuit.
Overload current adjustable from 49 to 59A
The rotary overload current setting corresponds to a motor rated current range of 49 to 59 amps.
Class 10 standard escape characteristics
It meets the standard trip level for general motor start-up time, providing reliable overload protection.
S2 frame compact design
It shares the same external dimensions as other models in the same series, which facilitates the planning of electrical distribution box space and the management of spare parts.
