Why Choose the ABB OT600U40P UL Switch-Disconnector?
The ABB OT600U40P is a heavy-duty 600 A UL switch-disconnector designed for dependable switching and isolation in demanding low-voltage electrical systems. Part of the established ABB OT600U range, it provides a robust non-fusible disconnecting solution for industrial power distribution, machinery, switchboards and electrical control systems.
The OT600U family is designed for front-operated, base-mounted installation and carries a 600 A general-purpose UL/CSA rating at up to 600 V AC. The range complies with UL 98, CSA C22.2 No. 4 and IEC 60947-3, supporting demanding industrial applications where a recognised high-current disconnecting means is required.
With substantial motor-switching capability and high short-circuit withstand performance, the OT600U40P is suitable for large machinery and distribution applications. Its manual switch-disconnector design provides positive electrical isolation without incorporating overcurrent protection, so appropriate upstream or system-level protective devices should be selected separately as required by the installation.

Reliable 600 A UL Switching and Electrical Isolation
The ABB OT600U40P provides a dependable means of manually switching and isolating high-current electrical circuits. As a non-fusible switch-disconnector, its function is switching and isolation rather than overcurrent protection, allowing downstream machinery and electrical equipment to be disconnected for maintenance, servicing and operational control.
The OT600U platform combines a 600 A UL/CSA rating with substantial motor-load capability and a 20 kA short-time withstand current for 1 s. These characteristics make the OT600U40P suitable for integration into high-current industrial switchboards, motor control systems, machinery and power distribution assemblies.
Typical Applications
- Industrial power distribution systems.
- UL 98 non-fusible disconnect applications.
- High-current machinery isolation.
- Industrial motor disconnecting applications.
- Main and sub-distribution switchboards.
- Motor control centres and electrical control systems.
- Manufacturing and process equipment.
