ABB OT200 Main Switch Disconnector

The ABB OT200 is a heavy-duty switch-disconnector rated at 200 A AC-23A for use as the main incoming isolation switch in distribution boards, motor control centers, machine panels, and industrial enclosures. Built to IEC 60947-3, the OT200 provides full load-breaking capability — it can make and break at full 200 A rated load, unlike a pure isolator — and the through-door operating mechanism allows safe switching with the panel door closed, a fundamental safety requirement under Saudi Arabia's electrical safety regulations and ARAMCO's SAES-B-068 safety standards. The three-padlock capability on the off-position handle satisfies LOTO (lockout-tagout) requirements mandated on all ARAMCO, SABIC, and SEC sites, allowing multiple maintenance trades to simultaneously lock out a circuit they are working on.

Technically, the OT200 covers supply voltages up to 1000 V AC and 250 V DC, making it suitable not only for standard 400 V LV distribution but also for 690 V industrial drives and DC battery and UPS systems. Its AC-23A utilization category (switching motor loads and mixed inductive loads) ensures reliable operation across the varied load types found in industrial panels, avoiding contact erosion failures that occur when lower-category switches are misapplied. The transparent window on the front cover provides visual confirmation of the main contact position — open or closed — without opening the panel door, meeting IEC 60947-3 visible isolation requirements that are increasingly enforced in SEC and ARAMCO facility audits. Auxiliary contacts, shunt trip coil, and undervoltage release accessories are available for remote switching, automatic shutdown on fault, and supervision within BMS or SCADA systems.

In Saudi Arabia, the OT200 is the de facto standard main switch in every category of LV panel from small machine control enclosures to large 2500 A main distribution boards (where multiple OT200 units serve as feeder isolation switches). Panel builders across Riyadh's MODON industrial zones, Jeddah's commercial tower electrical rooms, and Jubail's petrochemical facility MCRs assemble thousands of OT200 switches annually. The OT200 is listed in ABB's SASO-approved products register for Saudi Arabia, satisfying the documentation requirements of SASO-IEC 60947-3 for electrical products sold in the Kingdom. Door-coupling kits for panel door mounting are available in rotary handle and padlockable versions to match all standard IEC panel door thicknesses from 1.5 mm to 4 mm.

Razz Middle East holds OT200 in three-pole and four-pole versions with a complete range of door-coupling kits, auxiliary contact blocks, and shunt trip coils in our in-kingdom warehouse. We supply single units for maintenance replacement and bulk quantities for panel builders, with same-day dispatch for urgent requirements and SAR pricing on all order sizes.
