ABB OT200KAUA4D 200A Double Switch Assembly – Two Switches
The ABB OT200KAUA4D is a 200 A double switch assembly incorporating two switches, designed for electrical switching, isolation and distribution applications where two switching devices are required within a coordinated arrangement. Classified under ABB's Metal Enclosed (Loadbreak) product group, it belongs to the established ABB OT industrial switching family.
The 200 A current rating and dual-switch configuration make the OT200KAUA4D suitable for appropriately engineered low-voltage electrical installations requiring separate switching functions, coordinated isolation or dual-circuit control.
ABB's OT switch-disconnector technology is widely used in industrial power distribution, machinery isolation and electrical switching assemblies. The OT200KAUA4D offers a practical solution for electrical contractors, panel builders and maintenance engineers specifying a 200 A double-switch arrangement.

Understanding the ABB 200A Double Switch Configuration
The defining feature of the ABB OT200KAUA4D is its two-switch arrangement. Unlike a conventional single switch-disconnector, this configuration incorporates two switching devices for applications requiring a coordinated double-switch assembly.
Such arrangements may be used in electrical systems where two circuits, supply paths or switching functions must be managed within a common installation. The exact electrical operation depends on the manufacturer's internal connection arrangement, operating mechanism and the overall system design.
The designation DL SWITCH 2 SWITCHES identifies the assembly as a double-switch product. It should not automatically be interpreted as an interlocked changeover switch, automatic transfer switch or dual-supply transfer system without confirmation of the specific operating arrangement.
The specified 200 A rating provides a key selection parameter. Final suitability must also account for the operational voltage, utilisation category, connected load characteristics, short-circuit conditions and protective-device coordination.
Industrial Electrical Switching and Isolation
ABB's OT switch-disconnector family is designed for electrical switching and isolation in industrial applications. The OT200KAUA4D extends this functionality through its specified double-switch configuration.
For maintenance applications, switching devices can form part of an engineered electrical isolation arrangement. The complete installation must provide appropriate means of preventing unintended energisation, verifying isolation and protecting personnel during servicing.
Where the two switches are used with separate electrical supplies, designers must ensure that the arrangement prevents unsafe source connections and complies with the relevant electrical installation requirements. Any required mechanical or electrical interlocking must be verified for the exact assembly.
The OT200KAUA4D should not be treated as providing automatic overload or short-circuit protection. Suitable circuit breakers, fuses or other protective devices must be included where required.
Installation and Equipment Selection
The ABB OT200KAUA4D is intended for specification by qualified electrical professionals familiar with low-voltage switching equipment and industrial electrical distribution systems.
Before installation, the exact assembly should be assessed for its terminal arrangement, pole configuration, operating sequence, enclosure construction, cable-entry requirements and mounting provisions. These details determine how the two switches can be incorporated into the intended electrical circuit.
The supplied product specification confirms the 200 A rating and two-switch arrangement. Exact dimensions, IP rating, handle configuration and additional electrical ratings are not established by the supplied designation and should not be assumed from other ABB OT200 variants.
Correct installation, suitable protective-device coordination and compliance with the manufacturer's instructions are essential for dependable operation.
