Reliable Switching and Isolation for Electrical Distribution
Switch-disconnectors provide a dependable means of switching and isolating electrical circuits, allowing sections of a distribution system to be disconnected for operation, servicing or maintenance. The ABB MA160ALAB combines the modular CombiLine interior fitting system with an integrated OT160G switch-disconnector to provide a compact and practical isolation solution.
The fitted ABB OT160G is a 3-pole switch-disconnector rated at 160 A. Its compact construction and DIN rail mounting make it well suited to distribution applications where reliable switching performance and efficient use of cabinet space are important, while the equipped MA160ALAB module reduces the amount of component selection and assembly required during panel construction.
Typical Applications
- Commercial and industrial sub-distribution boards.
