3RV1946-2B

The Siemens 3RV1946-2B rotary operating mechanism is engineered primarily for use with Size S3 circuit breakers, facilitating the control and operation of these devices. This construct relies on a door coupling type, ensuring effective integration into existing setups. Weighing in at 1.722 kilograms, it offers a balance of robustness and usability during installation and servicing.

This mechanism is governed by an operational temperature capability, ranging from 0 to 60 degrees Celsius, accommodating various environmental conditions typically found in industrial settings. It carries a protection class rating of IP20, which signifies that it is primarily safeguarded against solid foreign objects greater than 12.5 mm, but not protected against moisture.

The 3RV1946-2B has been certified to meet CE standards, ensuring compliance with applicable directives for health, safety, and environmental protection. Encapsulated in a gray housing, it blends nicely into typical panel environments. When considering ecological tolerances, it can withstand humidity levels of up to 80% (non-condensing) during both operation and storage. Additionally, this mechanism is suitable for altitudes up to 1000 meters above sea level, maintaining reliable functionality at various installation heights.
