The Schneider Electric iSW DIN Rail Isolator Switch (A9S65291) is designed for electrical professionals needing a reliable 2-pole disconnect for control circuits and general isolation. Its key benefit is providing safe, visible isolation with a 100A capacity and IP20 protection for enclosed environments. A minor caveat is its standard configuration which may require adaptation for specific control logic needs.

The primary function is to provide a safe and visible means of disconnecting electrical circuits for maintenance, repair, or emergency shutdown.
No, this is an isolator switch and does not provide overcurrent or short-circuit protection. It must be used in conjunction with appropriate protective devices like circuit breakers or fuses.
IP20 means the switch is protected against solid objects larger than 12.5 mm (like a finger) but offers no protection against water ingress. It is suitable for use within electrical enclosures.
This is a 2-pole switch designed to simultaneously disconnect two conductors (typically Line and Neutral in AC systems). It's for isolating one complete circuit.
NO stands for 'Normally Open'. This means that when the switch is in its default (OFF or isolated) state, these two sets of contacts are open and do not conduct electricity. They close when the switch is operated to the ON position.
Specific warranty details are best obtained from the point of purchase or Schneider Electric directly, as warranty periods can vary by region and retailer.
Yes, the switch is designed to operate within a wide temperature range of -25°C to +60°C, making it suitable for many industrial environments.
Ensure the switch is correctly mounted on the DIN rail and not obstructed. Check that terminal connections are not over-tightened, causing strain. Verify the operating temperature is within the specified range.
Verify that the circuit is properly wired to the switch terminals. Check if the internal contacts are damaged (requires inspection by a qualified electrician). Ensure the rated voltage and current are not exceeded.
Do not use the switch if the handle is damaged. Replace the unit as a damaged handle can compromise safe operation and isolation. Contact Schneider Electric support for a replacement.
Setup:
The iSW isolator switch is designed for standard DIN rail (35mm) mounting. Ensure the DIN rail is securely installed in your enclosure. Snap the switch onto the rail by aligning the clip on the back of the switch with the rail and applying firm pressure until it clicks into place. Connect the line and load conductors to the appropriate terminals, observing proper torque specifications to ensure secure connections. The 2-pole configuration requires connections on both sides of the switch.
Compatibility:
This switch is compatible with standard electrical enclosures and distribution panels that accommodate DIN rail mounting. It is designed to work within a 415V AC system. Ensure that the circuit's maximum current does not exceed the switch's 100A rating. It is part of the Schneider Electric Acti 9 range, ensuring compatibility with other Acti 9 components.
