The Siemens SIRIUS 3RV2041-4YA10 Motor Protection Circuit Breaker (MPCB) is a heavy-duty industrial motor protection device designed to provide motor overload protection, short-circuit protection, phase failure protection, and safe electrical isolation for high-power three-phase motors. As part of the globally trusted Siemens SIRIUS 3RV2 series, this Size S3 Motor Protection Circuit Breaker combines a Class 10 thermal overload release with a 1300A magnetic short-circuit release, delivering reliable protection and long-term performance in demanding industrial environments. It is ideal for Motor Control Centers (MCC), industrial automation systems, process plants, OEM machinery, power distribution panels, manufacturing facilities, and heavy-duty motor starter applications.
The 3RV2041-4YA10 features an adjustable thermal overload current range of 75–93A, 1300A magnetic short-circuit release, 3-pole configuration, screw terminal connections, and standard switching capacity. It supports operating voltages from 20V to 690V AC, offers a 1000V rated insulation voltage, and is engineered with high mechanical and electrical endurance for continuous industrial operation. The breaker integrates seamlessly with compatible Siemens SIRIUS S3 contactors, enabling compact and efficient Direct-On-Line (DOL) and star-delta motor starter assemblies while reducing wiring complexity and panel space requirements.
Designed for reliable operation in harsh industrial conditions, the Siemens 3RV2041-4YA10 is widely used in large pumps, compressors, conveyor systems, HVAC equipment, mining machinery, cement plants, steel mills, water treatment facilities, packaging machines, process industries, and factory automation systems. Its rugged construction, high breaking performance, and Siemens engineering ensure maximum equipment protection, reduced maintenance costs, and improved operational efficiency.
