Siemens 1SCA135136R1001 High Voltage Transformer

ABB OT160GT03 three‑pole switch‑disconnector, catalog 1SCA135136R1001, is a door‑mounted, front‑operated isolation device designed for three‑phase circuits in switchgear and control panels. It supports a 160 A continuous current rating and provides electrical isolation with a voltage capability up to 600 VAC and 250 VDC for control circuits, with a nominal frequency of 50/60 Hz. The unit is specified for high‑voltage service up to 12 kV in applicable configurations, enabling use in medium‑to‑high‑voltage distribution schemes. The OT160GT03 is listed as 3P and is offered in variants intended for mounting in a door without a handle and shaft, depending on installation specifics. In ABB’s OT160G family, this model is used to physically disconnect a circuit during maintenance or protection tasks, with emphasis on reliable mechanical action and clear visibility of the isolated state. Typical applications include industrial control panels, feeder disconnects, and utility switchgear where a compact, front‑operating disconnect is required for safe maintenance and clear status indication.
