Siemens SEM3SCCT125-BP Solid Core Current Transformer

Siem​ens SEM3SCCT125-BP is a solid‑core current transformer designed for Siemens’ SEM3 branch‑circuit metering system, delivering accurate current sensing in 600 V AC power distribution that operates at 50–60 Hz. It carries the catalog designation SEM3SCCT125 (US2: SEM3SCCT125) with the ratio notation 125:0.1, reflecting its 125 A primary rating and the documented measurement ratio. This compact, solid‑core CT is intended for integration into SEM3 meters and other SEM3 components used for submetering and energy insights, and it sits within Siemens’ modular SEM3 CT lineup alongside other primary amperage options for revenue‑grade monitoring in panelboards, switchboards, PDUs, bus plugs, and retrofit enclosures. The SEM3SCCT125‑BP variant is documented in Siemens data and distributor listings as part of the SEM3 solid‑core CT family, ensuring compatibility with the SEM3 meters and the broader SEM3 portfolio. In application, it enables reliable current measurement for up to the 125 A range in 50–60 Hz distribution networks, supporting precise energy monitoring and reporting within Siemens’ SEM3 ecosystem.
