Siemens AG 3RV1041-4JA10 Sirius Motor Starter

The Siemens SIRIUS 3RV1041-4JA10 Motor Starter Protector is a compact S3‑size device that provides integrated thermal overload protection for three‑phase motors alongside basic starting control. It is rated for 45–63 A, falls under Class 10 protection, and is designed to trip within a calibrated time frame to prevent motor damage under overload conditions. The unit features screw-terminal wiring for secure panel installation and is part of Siemens' SIRIUS 3RV motor protector family, a compact solution used in pumps, fans, conveyors, and other common industrial motor loads. By combining protection with a ready‑to‑wire starter format, the 3RV1041-4JA10 helps simplify motor protection schemes in standard control panels while maintaining compatibility with other Sirius components.
