Schneider Electric 28908-PL-W20-4 Switch Disconnector

Schneider Electric 28908 INS100 switch disconnector is a compact, three‑pole isolation device rated for 100 A, designed for panel or DIN-rail mounting as part of the ComPacT INS Compact family. It features a black rotary handle for manual operation and a footprint of 135 mm wide, 100 mm high, and 62.5 mm deep, enabling tight panel installations. The device is suitable for AC circuits up to 690 V (50/60 Hz) and provides a high interrupting capability of up to 20 kA when used as a switch‑disconnector alone, making it a robust isolation solution for distribution panels. The INS100 variant supports mounting on both DIN rails and panels and is compatible with standard ComPacT accessories for auxiliaries and trip circuits, supporting reliable isolation in 3P distribution schemes. This model is commonly used in control panels and switchgear where deliberate, maintenance‑safe isolation of downstream circuits is required, and it reflects Schneider Electric’s ComPacT INS Compact lineage designed for efficient wiring and straightforward integration into existing electrical architectures.
