Why choose it

The OT Plus series is engineered for reliable isolation in compact spaces. Its eight-pole design allows simultaneous switching of multiple circuits, reducing installation time and wiring complexity. The direct mounted handle provides clear ON/OFF indication and can be padlocked in the OFF position for maintenance safety. With a high withstand rating and wide temperature range, it performs consistently in harsh industrial settings.

Ideal use cases

• Isolating multiple DC strings in solar combiner boxes
• Disconnecting battery banks in UPS systems
• Switching control circuits in motor control centers
• Safety isolation in machine tools and conveyor systems

Good to know

The switch meets IEC 60947-3 and offers IP65 protection on the front when the handle is installed, making it suitable for panel doors. Screw terminals accept conductors from 1.5 to 35 mm², ensuring compatibility with a wide range of wiring. For auxiliary contacts or additional accessories, refer to ABB's OT Plus accessory range.
