Siemens SIRIUS Motor Protection Circuit Breaker – Size
S00 – 3RV2111-4AA10
The Siemens 3RV2111-4AA10 is a SIRIUS 3RV2 series
motor protection circuit breaker (MPCB) designed for reliable protection of
three-phase motors against overload, short-circuit, and phase failure
conditions. It is commonly used in MCC panels, motor starter assemblies,
industrial automation systems, pumps, compressors, conveyors, and HVAC
equipment where precise and compact motor protection is required.
This device belongs to the Size S00 frame and features
a thermal magnetic trip unit with Class 10 tripping characteristics,
ensuring fast and safe motor disconnection under fault conditions.
It provides adjustable overload protection in the range
of 10–16 A along with a fixed magnetic short-circuit release of 208 A,
making it suitable for medium-sized motor applications with stable
protection performance.
