ABB - OT Plus Changeover Switches: Flexible, Reliable, and Future-Ready
One Solution - Multiple Applications
With the OT Plus series, ABB introduces a new generation of changeover switches designed to meet the demands of modern industrial applications. This updated line combines reliability with flexibility and supports efficient and safe installation – regardless of environment or application.
One Series, Maximum Flexibility
The OT Plus changeover switches are available in three- and four-pole versions with ratings from 16A up to 160A. They stand out thanks to the adjustable fourth pole, which can operate either as a simultaneous switching point or with a time delay (early-make / late-break). This makes one type of switch suitable for multiple applications. With overlapping current ranges, user-friendly auxiliary contacts, and a well-thought-out modular design, this series is perfectly suited for integration in switchgear and panel building applications.
Designed for Continuity and Safety
The OT Plus series is equipped with a ‘true’ fourth pole that helps prevent electrical faults and ensures high operational reliability. The lockable operating handle increases on-site safety. The robust mechanical design guarantees a long service life, with a mechanical endurance of up to 20,000 operations.
Sustainable and Future-Proof
With the new OT Plus series, ABB emphasizes its commitment to sustainability and circularity. The switches are largely made from recycled materials and are more than 95% recyclable. Thanks to the energy-efficient design, power loss is reduced by up to 27%. This makes OT Plus not only a future-proof choice but also an environmentally conscious investment.
Take the Leap Forward
The OT Plus changeover switches combine innovative technology with practical installation benefits and long-term performance. With their modular design, wide application range, and sustainable construction, they are an ideal choice for installers and panel builders seeking quality, efficiency, and reliability in electrical installations.
