Why Choose the ABB OT250KAUR3TZ 250A 3-Pole IP65 Enclosed Safety Switch?
The ABB OT250KAUR3TZ is a heavy-duty 250 A three-pole steel enclosed safety switch-disconnector designed for dependable load switching and electrical isolation in demanding industrial installations. Part of the ABB OT enclosed safety switch range, it combines high-capacity switching performance with a robust steel sheet enclosure for machinery, motor control and low-voltage power distribution applications.
Designed for safe local isolation, the OT250KAUR3TZ features a black pistol-type I-O / ON-OFF operating handle and factory-fitted 2NO+1NC auxiliary contacts. Its cable-entry arrangement uses a blank top entry and four ring-flange openings at the bottom, allowing suitable compression glands or flanges to be selected separately for the installation.
With a rated current of 250 A, the OT250KAUR3TZ provides AC-23A motor switching capability of 132 kW / 250 A at 415 V and 200 kW / 250 A at 690 V. Its IP65 steel enclosure measures approximately 800 × 400 × 230 mm, providing a durable enclosed isolation solution for substantial three-phase industrial loads.
