Optional handles available for the Mini OS and Standard OS series of fused switch disconnectors.

Takes up to 3 padlocks
Locking in off position or 3 position options available

Install this replacement handle from ABB to fix or upgrade your existing isolator switch. Made for use with ABB's OT160E series of isolator switches (762-2660 and 762-2666), it works as part of a system that isolates electrical circuits to make them safe for maintenance or repair. For added safety, the handle can be locked with up to three padlocks when switched off. This prevents the accidental activation of machines during servicing and keeps users safe.

• Attaching screws positioned in the handle's back side for extra electrical insulation
• IP65 (ingress protection) rated, meaning the handle is dust-tight and protected against limited water jets
• 65mm handle length for easy operation in emergencies

• Power grids and substations
• Domestic appliances
• Manufacturing industry

Isolator switches and circuit breakers both break circuits but they do so for different reasons. Circuit breakers automatically trip if they detect excessive currents to prevent damage to your components. On the other hand, isolator switches like this one are used to manually isolate circuits to let you work on your machinery safely.

ABB OS Range

A fused switch disconnector provides a cost effective means of short circuit protection, together with circuit isolation. The choice of fuse rating determines the level of protection, the maximum value is determined by the fused switch disconnector. These items have been tested in accordance with EN 60947-3.
