A range of extensions shafts and selector handles for use with the OT range of switches.

Shaft fitted to the disconnector to enable operation, used in conjunction with a handle
Handles available in black or yellow/red

Use this shaft from ABB with a switch disconnector to cut power to your electrical circuit for maintenance or inspection. For ease of assembly, it's designed for use with products in the OT series. To enable operation, combine this unit with a selector-type handle before fitting it to the switch disconnector. The compatible products have a robust mechanical endurance of up to 20,000 switching cycles for long-lasting performance. They also have a rated impulse withstand voltage of 8kV, so they can handle powerful surges to help protect your equipment against damage.

• Compact dimensions of 180 (length) x 6mm (diameter) for installation in tight spaces
• Light weight of just 50kg to put minimal strain on your equipment

• Emergency stop push buttons
• Industrial control systems
• Food and beverage manufacturing
• Switchboards

Some of the selector-type handles in the OT series have an IP54 rating, indicating protection against limited amounts of dust and water sprays. Others have an IP65 rating, so they're dust-tight and protected against low-pressure water jets. You should choose a handle with the appropriate level of protection for your work environment.

The OT range of switch disconnectors are suitable for use in a variety of applications including motor control centres, switchboards and as main switches in machines.
