Why Choose the ABB OTR75A3B Safety Switch?
The ABB OTR75A3B is a robust 80 A safety switch designed for reliable electrical isolation and load switching in industrial installations. Part of the ABB OTR enclosed switch-disconnector series, it provides a practical enclosed solution for machinery, power distribution, motor circuits and industrial control applications.
Designed for dependable local isolation, the OTR75A3B combines the switching mechanism, operating system and protective enclosure in a single assembly. This enclosed construction makes it suitable for installation close to industrial equipment where operators and maintenance personnel require a clearly defined means of disconnecting the electrical supply.
With its 80 A rating, the OTR75A3B is suited to higher-current industrial circuits where safe, accessible switching and isolation are required. As part of ABB product group 311019-Metal Enclosed (Loadbreak), it is designed to provide both isolation and load-break functionality within an enclosed industrial switching solution.

Reliable Safety Isolation for Industrial Systems
Safety switches and enclosed switch disconnectors provide a clearly identifiable means of disconnecting electrical equipment from its supply. The ABB OTR75A3B combines an 80 A switching device with enclosed construction, providing a practical local isolation point for industrial machinery and electrical distribution equipment.
Local isolation is particularly important during inspection, servicing and maintenance activities where electrical equipment must be disconnected before work begins. The OTR75A3B is designed for these industrial applications while also providing load-break switching capability for normal electrical operation.
Typical Applications
- Industrial machinery isolation and main switching.
- Motor and production equipment isolation.
- Industrial electrical distribution systems.
- Manufacturing and processing machinery.
- Pumps, fans and ventilation equipment.
- Conveyors and material handling systems.
- Industrial control and automation installations.
- Local maintenance and electrical isolation points.
