Siemens 3RV1011-1DA10 Motor Protection Circuit Breaker

Siemens 3RV1011-1DA10 is a three‑pole motor protection circuit breaker (MPCB) in the Sirius 3RV1 family, size S00, designed to protect small to medium three‑phase motors in industrial control panels. It is rated for mains voltages up to 690 V AC and features screw terminals for secure field wiring, suitable for DIN rail mounting in standard control enclosures. The device combines thermal overload protection with a Class 10 release (A‑rel) adjustable from 2.2 to 3.2 A, and a secondary short‑circuit release (N‑rel) rated at 42 A, enabling coordinated protection against both overloads and high‑fault currents. As a compact MPCB, it provides motor protection and disconnection in one device, reducing the need for separate overload relays. Typical applications include protection of three‑phase motors in networks up to 690 V within conveyors, pumps, fans, and machine‑tool circuits, where compact size and Siemens compatibility are advantages. Its configuration and termination approach are designed to integrate with Siemens control schemes, offering a straightforward, enclosure‑friendly solution for panel builders seeking reliable motor protection without external devices.
