ABB OTR16GA3M Maintenance Switch
Product Description
The ABB OTR16GA3M is a maintenance switch designed for safe and reliable isolation in industrial installations. It features a 3-pole design and a rugged stainless steel enclosure for use in demanding indoor and outdoor environments. The interlocked cover helps prevent access when the switch is in the ON position, supporting safer maintenance routines and reducing the risk of unintended operation.
The enclosure is built from AISI 304 stainless steel and includes a hinged door with door lock for practical access control. A defeatable interlocking function is provided for thermographing when required. The unit is supplied with a PE terminal and auxiliary contact, and can be used in EMC applications when suitable EMC cable glands are installed. Cable entry is via knockout-type openings for flexible installation.
