Product Positioning

The SIRIUS 3RV2021-4FA16 is a Siemens S0 frame motor protection circuit breaker with an adjustable current range of 34 to 40A. It is one of the specifications with the highest current adjustment limit in this series and is suitable for overload and short circuit protection of medium and large three-phase motors.

Core Product Advantages and Features

High current adjustable range

With an overload current adjustable from 34 to 40A, it is one of the models with a relatively high adjustable range in the 3RV2021 series, making it suitable for larger power motors.

CLASS 10 breakout feature

When an overload occurs, it operates according to the CLASS 10 standard time, taking into account both startup stability and protection response speed.

Transient short circuit protection

With an instantaneous trip response value of 480A, it can quickly disconnect the power supply in the event of a short circuit fault, reducing equipment damage.

S0 frame compact design

Maintain the S0 standard frame size for easy assembly with components such as contactors of the same frame.
