Siemens 3RV2011-1KA10 Manual Motor Protector

Siemens 3RV2011-1KA10 is a three‑pole manual motor protector (motor protection circuit breaker) designed for DIN‑rail mounting in control panels, sized for the S00 frame to guard three‑phase motors in compact installations. It combines thermal overload protection with a short‑circuit release in a single device, offering an adjustable thermal (A‑release) setting from 9 to 12.5 A and a fixed instantaneous (N‑release) rating of 163 A, delivering Class 10 protection for motor loads. The unit uses screw terminals for secure wiring and is part of Siemens’ SIRIUS motor‑protector family, a common choice for panel builders needing integrated motor protection in a small footprint. This 3‑pole MPCB is suitable for three‑phase motor applications such as conveyors, pumps, fans, and similar equipment mounted in control cabinets, providing reliable protection within standard DIN rail enclosures. Designed for precise current settings and robust short‑circuit response, the 3RV2011‑1KA10 pairs a compact S00 form factor with dependable Siemens engineering to meet typical motor‑protection requirements in industrial automation.
