The Siemens SIRIUS 3RV2111-0BA10 Motor Protection Circuit Breaker (MPCB) is a premium industrial motor protection device engineered to provide overload protection, short-circuit protection, phase failure protection, and safe isolation for low-power three-phase motors. Part of the globally trusted Siemens SIRIUS 3RV2 series, this Size S00 Motor Protection Circuit Breaker combines a Class 10 thermal overload relay with an integrated magnetic short-circuit release, eliminating the need for separate overload protection devices while ensuring reliable motor safety and uninterrupted operation.
The 3RV2111-0BA10 features an adjustable thermal overload current range of 0.14–0.20A, a 2.6A magnetic short-circuit release, 3-pole construction, screw terminal connections, and standard switching capacity. It is designed for operating voltages up to 690V AC and provides dependable protection against overload, locked rotor, phase loss, and short-circuit conditions. Its compact S00 frame size allows easy installation in space-constrained electrical panels and seamless integration with Siemens SIRIUS contactors to create compact Direct-On-Line (DOL) and star-delta motor starter assemblies.
Designed for demanding industrial environments, the Siemens 3RV2111-0BA10 is widely used in motor control centers (MCC), industrial automation systems, OEM machinery, electrical control panels, laboratory equipment, instrumentation systems, miniature pumps, packaging machines, conveyor systems, textile machinery, food processing equipment, water treatment plants, HVAC systems, and factory automation. Its high mechanical endurance, reliable switching performance, and Siemens engineering ensure maximum equipment protection, reduced maintenance, and long service life.
