Schneider Electric offers a broad range of isolators (also known as switch disconnectors). These devices are essentially manual "off switches" used to completely de-energize an electrical circuit for safety, primarily during maintenance or repair work.
​Unlike circuit breakers, isolators do not automatically trip during a fault; their sole purpose is to physically break the connection to ensure no electricity flows to the equipment you are working on.
​1. Key Product Ranges
​Schneider Electric categorizes their isolators based on the application (residential, motor control, or heavy industry).
​A. Acti9 iSW (Modular Isolators)
​These look almost identical to standard Miniature Circuit Breakers (MCBs) but are used as the main switch in distribution boards.
​Best for: Residential and commercial distribution boards (DBs).
​Mounting: DIN Rail.
​Current Ratings: Typically 20A to 125A.
​Poles: 1P, 2P, 3P, 4P.
​Visual Check: Usually has a red toggle switch or a specific "Switch Disconnector" symbol printed on the front.
​B. TeSys Vario (Rotary Switches)
​These are rotary (turn-dial) switches often mounted on machine panels or enclosures.
​Best for: Motor control, industrial machinery, and "Emergency Stop" applications.
​Features: often come with a Red/Yellow handle (for emergency stop) or Black/Grey handle (for standard stop).
​Lockable: The handle can usually be padlocked in the "OFF" position for safety (Lockout/Tagout).
​Current Ratings: 12A up to 175A.
​C. ComPacT INS/INV (Molded Case Switch Disconnectors)
​These are heavy-duty blocks used in main electrical panels.
​Best for: Industrial main distribution panels and high-power applications.
​Current Ratings: 40A up to 2500A.
​Safety: Visible break mechanism ensures you can see the physical separation of contacts.
​2. Isolator vs. Circuit Breaker (MCB)
​It is critical not to confuse the two, as they look similar but function differently.
