Siemens SIRIUS Motor Protection Circuit Breaker – Size
S00 – 3RV2111-1CA10
The Siemens 3RV2111-1CA10 is a SIRIUS 3RV2 series
motor protection circuit breaker (MPCB) designed for safe and reliable
protection of three-phase motors against overload, short-circuit, and
phase failure conditions. It is widely used in MCC panels, motor
starters, industrial automation systems, pumps, compressors, conveyors, and
HVAC applications where 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 dependable motor disconnection during fault conditions.
It provides adjustable overload protection in the range
of 1.8–2.5 A along with a fixed short-circuit release of 33 A,
making it suitable for small motor applications with precise protection
requirements.
