Schneider Electric 2-pole switch disconnector iSW A9S65240 40A 240V

Schneider Electric 2-pole switch disconnector iSW A9S65240 rated 40A and 240V provides manual isolation and switching of two poles in low-voltage electrical installations. Designed for mounting in switchboards and distribution panels, this device enables safe operational isolation and circuit control for industrial and commercial environments. The compact form factor and standardized front mounting allow integration into common electrical panels where disconnection of both live conductors is required.

Advantages

The switch disconnector offers reliable manual breaking of two conductors with a clear mechanical indication of position. It is built to meet typical industrial durability expectations and permits visible isolation for maintenance tasks. Installation is straightforward due to its panel-mount design and compatibility with standard mounting cutouts, while the rated current and voltage ensure applicability across a range of low-voltage circuits.

Suitable for

• Isolation and switching of small distribution circuits in industrial and commercial switchboards
• Providing a visible means of disconnection for equipment maintenance
• Use in control panels requiring two-pole breaking for safety or code compliance

When it may not be suitable

This device is intended for manual switching and isolation in low-voltage systems up to the specified ratings; it is not designed as a protective device against short-circuit without appropriate upstream protection. It may not be suitable where automatic switching, motor protection functions, or higher current/voltage ratings are required.

Key specifications

• Poles: 2-pole switching/disconnection
• Rated operational current: 40 A
• Rated operational voltage: 240 V (AC)
• Mounting: panel/switchboard front mounting
• Operation: manual handle with position indication

How to use

Mount the switch disconnector into the appropriate cutout in the switchboard and secure it according to panel installation procedures. Connect the incoming and outgoing conductors to the designated terminals, ensuring tight and correct polarity connections for both poles. Use the manual handle to open (isolate) or close (connect) the circuit; confirm the mechanical position indicator before performing maintenance. Always ensure that upstream protection devices are rated correctly and that installation is performed by a qualified electrician in accordance with local regulations.

What to consider before purchase

• Verify that 40 A and 240 V ratings match the circuit requirements
• Confirm two-pole disconnection is required for the intended application
• Ensure panel cutout and mounting style are compatible with your switchboard
• Check that upstream protective devices and wiring are appropriate for safe operation

Usage recommendations

For safe operation, use the disconnector only for manual isolation and ensure regular inspection for secure terminal connections and mechanical integrity; coordinate with protective devices to provide overload and short-circuit protection.
