ABB OT40F3 Motor Disconnect Switch Non-Fusible

ABB OT40F3 is a three-pole, non-fusible motor disconnect switch rated for 40 A at up to 600 VAC, providing a dedicated isolation point for 3‑phase circuits in machinery, switchboards, motor control centers, and power distribution. This non-fusible disconnect (catalog number 1SCA104902R1001; alternate catalog OT40F3) is part of ABB’s SWITCHLINE OT series and is designed for front operation and base mounting, with DIN-rail mounting capability and protected clamp terminals; the handle and shaft are not included. It carries an IP20 enclosure rating and uses screw-terminal connections for straightforward installation, and it is compatible with UL/NEMA types including Type 1, 3R, 4, 4X, and 12 in appropriate configurations. Typical applications include motor isolation in control panels, industrial machinery, photovoltaic installations, and general power distribution where a reliable, code-compliant disconnect is required, delivering a simple, accessible means to interrupt power for service and maintenance. Its compact footprint and standard mounting options help integrate into new builds or retrofit projects within industrial facilities.
