Siemens OLR0630CC0 Overload Relay Switch 4-6 Range

Siemens OLR0630CC0 Overload Relay Switch is a compact motor‑protection relay designed to mount on Siemens contactors for safeguarding small motors against overload, with a form factor that fits neatly beside the main contactor in compact control panels. It offers an adjustable current range of 4.5 to 6.3 A (often described in documentation as 4–6 A) paired with a Class 10 thermal rating, making it suitable for frequent switching duty in industrial environments; the size is aligned with Siemens S00 contactors to keep panel footprints small. The unit uses screw-terminal connections for the main circuit and the auxiliary circuit, supporting both manual and automatic reset to suit different startup and fault-recovery preferences, and is designed to facilitate straightforward field wiring and service. Intended for motor protection in industrial control panels, the OLR0630CC0 is typically paired with Siemens contactors in the 3RU6116-1GB0 family to deliver reliable overload protection for applications such as conveyors, pumps, and fans, where compact design and compatibility with Siemens components are essential. The model is commonly referenced in Siemens Industry Mall listings as part of the 3RU6116-1GB0 overload family, underscoring its role in compact, integrated protection schemes that keep motor-driven equipment safe while preserving space in control cabinets.
