Reliable Motorised Isolation for Three-Phase Power Systems
Motorised switch-disconnectors combine electrical isolation with powered operation, allowing a circuit to be switched remotely from automation, supervisory or power-management equipment. This is useful in installations where routine switching needs to take place without an operator manually actuating the switch at the electrical panel.
The ABB OTM63F3M230V combines compact three-pole switching with a wide-range motor supply and manual operating capability. Its AC-21A, AC-22A and AC-23A ratings make it suitable for a broad range of three-phase loads, while the base-mounted design and protected terminals support straightforward integration into control panels and distribution equipment.
Typical Applications
- Three-phase electrical distribution boards.
- Industrial control panels.
- Remote-controlled electrical isolation.
- Automated power distribution systems.
- Motor and machinery supply switching.
- Building services and infrastructure equipment.
- OEM machinery and electrical assemblies.
