Product Positioning

The SIRIUS 3RV2031-4DB10 is a motor protection circuit breaker in the SIRIUS 3RV2031 series of Siemens S2 models. It has an adjustable current range of 18-25A, adopts Class 20 tripping characteristics, and is suitable for loads with long start-up times.

Core Product Advantages and Features

Adjustable current range: 18-25A

The overload trip value is adjusted within the range of 18-25A according to the motor's rated current to precisely meet the load requirements.

Class 20 Escape Feature

Compared to Class 10, its delayed thermal overload release characteristics make it suitable for motors with higher starting current or longer starting time.

S2 model design

It shares the same dimensions as the 3RV2031 series, making it easy to assemble with other components in the same series.

Screw terminal wiring

The main circuit uses screw terminals, making wiring for construction and maintenance convenient.
