ABB OT1600U3 Switch-Disconnector 1600A 3P
The ABB OT1600U3 is a switch-disconnector (Switch-Disconnector 1600A 3P) engineered by ABB, the global leader in electrification and automation technology and the most trusted electrical brand across Saudi Arabia's industrial sector. ABB OT1600U3 open-version switch-disconnector rated 1600 A, 3-pole, providing safe on-load isolation and visible contact indication to IEC 60947-3. Supplied as a genuine, fully type-tested ABB product by Razz Middle East, the OT1600U3 is held in local stock for fast delivery to industrial, commercial and infrastructure projects throughout the Kingdom of Saudi Arabia, from the Eastern Province energy corridor to the NEOM and Red Sea giga-projects.
Technical Overview
At the core of the OT1600U3 is ABB's proven switch-disconnector platform, refined over decades of deployment in the world's most demanding industries. ABB OT1600U3 open-version switch-disconnector rated 1600 A, 3-pole, providing safe on-load isolation and visible contact indication to IEC 60947-3. The design emphasizes long electrical and mechanical endurance, consistent calibration and full coordination with the wider ABB low-voltage range, so a single product family can be standardized across an entire facility. Headline parameters are: Rated current (AC-21A): 1600 A; Poles: 3; Utilization category: AC-23A; Rated insulation voltage: 1000 V; Standard: IEC 60947-3. Compared with generic alternatives, the OT1600U3 offers tighter manufacturing tolerances, tropicalized internals for high-humidity and salt-laden coastal air, and a documented type-test pedigree to international standards — the difference between a component that merely fits the schematic and one that survives years of continuous duty in a Saudi plant.
Performance & Specifications
Key performance figures for the OT1600U3 are drawn directly from the ABB datasheet: Rated current (AC-21A): 1600 A; Poles: 3; Utilization category: AC-23A; Rated insulation voltage: 1000 V; Standard: IEC 60947-3. These ratings are validated by type testing and hold across the wide -25 to +60 °C ambient range, high humidity and dust loading typical of Saudi Arabian industrial sites. The product carries the relevant international certifications (CE, cULus, CCC, marine), ensuring acceptance under SASO import requirements and Saudi Aramco engineering standards (SAES). Full datasheets, type-test certificates and dimensional drawings are available from Razz Middle East on request to support engineering, approval and procurement.
Applications in Saudi Arabia
Across the Kingdom the ABB OT1600U3 is specified in the most critical national assets. Main switch and incomer isolation in low-voltage switchboards at Aramco, SABIC and SEC facilities, where the OT1600U3 provides safe on-load switching and clear, visible isolation for maintenance, testing and emergency shutdown of feeders. Generator and utility changeover switching in standby power systems for hospitals, data centers and NEOM developments, ensuring a clear break between sources. Motor and machine disconnection at the point of use in industrial plants across Jubail and Yanbu, enabling lockable local isolation for safe maintenance. Distribution feeder isolation in MCCs and panel boards built by KSA panel makers, padlockable for lockout-tagout to Saudi safety standards. From Saudi Aramco oil and gas installations and SABIC petrochemical complexes to MAADEN mining operations, SWCC desalination plants, SEC power generation and the NEOM giga-project, ABB electrical equipment forms the backbone of power distribution, motor control and process automation, where uptime, safety and energy efficiency are paramount.

Key Features & Benefits
- The OT1600U3 provides safe on-load making and breaking to utilization category AC-23A, allowing the full motor or distribution load to be switched and isolated by hand at Saudi switchboards without arcing damage or operator risk.
- A positive, visible double-break contact mechanism gives a clear ON/OFF indication and a guaranteed isolation distance, satisfying the safe-isolation and proof-of-disconnection requirements of Saudi Aramco and SEC maintenance and permit-to-work procedures.
- The handle is padlockable in the OFF position for lockout-tagout, enabling crews to safely isolate feeders and machines during maintenance at petrochemical, mining and desalination plants in line with Saudi facility safety standards.
- Direct-mount or door-coupled IP65 handles, plus a wide range of auxiliary contacts and motor operators, allow flexible integration into both compact and large switchgear assemblies built by KSA panel makers for any project size.
- Robust open-construction design and high short-circuit withstand make it suitable as a main switch, transfer switch or distribution incomer in demanding industrial environments, including high-dust and high-temperature Eastern Province installations.
- A wide temperature rating and tropicalized contacts maintain reliable operation in the high ambient heat and dust of Eastern Province and Red Sea coast installations backed by SASO documentation, Saudi Aramco material approvals and an in-Kingdom engineering team for sizing and after-sales support.
