ABB OT16ET3 3 Pole 16 Amp 600 V Disconnect Switch

ABB OT16ET3 is a three-pole disconnect switch rated for 16 A at 600 V, designed to provide a safe, visible isolation point for three‑phase circuits in electrical distribution and switchgear. Catalog number 1SCA022352R6610 identifies OT16ET3 within ABB’s OT family of disconnect switches, which are used to isolate loads or sections of power systems during maintenance or fault isolation. With three poles, the device disconnects all live conductors simultaneously, ensuring a complete shutdown of the downstream circuit and a clear open state for safe work. Typical applications include isolating motors, feeders, transformers, and switchgear sections within panelboards and distribution boards in industrial, commercial, and utility environments. The model supports a 3-pole configuration, a 16 A current rating, and a 600 V maximum operating voltage, values that align with ABB low-voltage distribution standards and common wiring practices for three-phase systems.
