SIEMENS 3RV2011-0GA20-Z W97 Motor Protection Circuit Breaker (MPCB)

‌1. Product Name‌
SIEMENS 3RV2011-0GA20-Z W97 Motor Protection Circuit Breaker (MPCB)

‌2. Product Brief Introduction‌
The SIEMENS 3RV2011-0GA20-Z W97 is a Motor Protection Circuit Breaker (MPCB) from the Siemens SIRIUS 3RV series. It is an all-in-one device designed for the protection and control of three-phase electric motors, integrating short-circuit protection, adjustable thermal overload protection, a switching function, and isolation capability into a compact unit.

‌3. Product Description‌
The SIEMENS 3RV2011-0GA20-Z W97 is a robust and versatile Motor Protection Circuit Breaker (MPCB) within the Siemens SIRIUS 3RV product family. It provides a comprehensive and space-saving solution for protecting electric motors by combining multiple essential safety and control functions into a single device. Its primary role is to offer coordinated protection for a ‌SIEMENS MOTOR‌. The device features instantaneous magnetic trip protection that responds to high-level short-circuit faults, safeguarding the ‌SIEMENS MOTOR‌ windings and the electrical installation from catastrophic damage. Simultaneously, its adjustable thermal overload protection guards against sustained overloads and phase failure (single-phasing) - common causes of motor overheating and failure. The thermal element is precisely calibrated to the current drawn by the ‌SIEMENS MOTOR‌, tripping after a time delay proportional to the overload severity to prevent insulation damage. Beyond protection, this MPCB serves as a reliable manual ON/OFF switch for the motor circuit and provides safe isolation for maintenance purposes (with potential locking capability). The adjustable current setting allows fine-tuning to the exact full-load ampere (FLA) rating of the specific ‌SIEMENS MOTOR‌. Built for demanding industrial environments, it offers clear status and trip indication. As part of the modular SIRIUS system, it simplifies panel design, reduces wiring complexity, and minimizes component count compared to traditional setups using separate fuses, contactors, and overload relays. The "Z W97" suffix may indicate specific configuration or accessory options. By integrating switching and coordinated protection, the 3RV2011-0GA20-Z W97 enhances operational safety, reduces downtime, and extends the lifespan of the connected ‌SIEMENS MOTOR‌.
