Product Positioning

The 3RV2021-4EA16 is a Siemens SIRIUS series S0 enclosure motor protection circuit breaker with a current adjustment range of 27~32A. It also features thermal overload protection and electromagnetic instantaneous short-circuit tripping functions.

Core Product Advantages and Features

Wide current adjustment

The current adjustment knob can be continuously set within the range of 27~32A, corresponding to the actual rated current of the motor, thus improving the accuracy of overload protection.

Electromagnetic instantaneous trip

When the short-circuit current reaches the set value, the electromagnetic tripping mechanism can instantly cut off the circuit, reducing the damage to the equipment caused by the short-circuit accident.

S0 standard enclosure

It adopts the SIRIUS series S0 standard housing design and can be used in combination with accessories and auxiliary contact modules of the same series.

DIN rail mounting

It supports 35mm standard rail clip installation and can also be fixed with screws, making it easy to integrate and configure in the distribution box.
