The OT Plus switch disconnector series represents the latest generation of ABB’s well-known switch disconnectors. Combining advanced protection with innovative technology, the series is ideal for both distribution and sub-distribution applications. It is available in 3, 4, 6 or 8 pole configurations.
The series is marked with an impulse withstand voltage of 8 kV, making it suitable as an input switch in switchboards with insulation coordination. In addition, the series is 100% compatible with the shafts and door handles used for the classic OT switch disconnector.
KEY BENEFITS:
• FLEXIBILITY
Flexible series with three different frame types, making it easy to find the right switch disconnector for both replacement and new installations. Available in sizes from 16 to 160 A.
• INCREASED SAFETY
The unique fourth pole increases the safety of both people and property, and reduces the risk of errors. The adjustable timing allows for early-make/late-break functionality, ideal for switching sensitive equipment.
• LESS CLIMATE LOAD
Reduce your environmental impact with a range that minimizes heat loss by up to 27%. The OT Plus range is designed for the circular economy, manufactured with a high proportion of recycled materials and is over 95% recyclable. It is part of ABB EcoSolutions and comes with an ECOpassport (3rd party verified EPD).
