This Schneider Electric iSW 4-pole isolator switch is designed for electrical professionals needing reliable circuit isolation in various applications. Its key benefit is providing a safe, manual disconnection point for up to 40A at 415V, with a robust IP20 rating. A potential caveat is its specific flush-mounting design, requiring dedicated installation space.

Its primary function is to provide a safe, manual means of disconnecting electrical circuits for maintenance, repair, or isolation purposes.
IP20 means the switch is protected against solid objects larger than 12.5mm (like a finger) but offers no protection against water ingress. It should be installed in a dry, protected environment.
This specific model is rated for 415V and is typically designed for AC circuits. Using it on DC circuits may not be appropriate and could be unsafe. Always consult the product documentation for specific application guidance.
The switch is rated for a maximum continuous current of 40 Amperes (40A).
A 4-pole switch is designed to simultaneously disconnect or connect all four conductors of a multi-phase system (e.g., three phases plus neutral, or multiple individual circuits).
The switch has a width of 72 mm, a depth of 73 mm, and a height of 85 mm.
No, due to its IP20 rating, it is not suitable for outdoor use or in environments exposed to moisture or dust.
Ensure the switch is not overloaded beyond its 40A rating. Check for any obstructions or debris around the operating mechanism. Verify correct installation alignment.
Confirm that the circuit breaker or upstream protection device is energized. Check all terminal connections for tightness and correct wiring. Verify the switch is in the 'ON' position.
Turn off power immediately. Check terminal connections for proper torque. Ensure conductors are correctly sized for the 40A load. Inspect for any signs of damage or corrosion.
Setup: This device is designed for flush mounting within electrical enclosures. Ensure the enclosure has the appropriate cut-out and mounting points for its dimensions (72mm Width, 73mm Depth, 85mm Height). Connect the incoming and outgoing power conductors to the respective terminals, observing correct polarity and torque specifications. The 4 poles should be wired according to the specific circuit requirements.
Compatibility: The iSW series is designed to integrate with standard modular electrical installations. It is compatible with systems operating at up to 415V AC and rated for 40A. Always ensure compatibility with the overall system's fault current rating. It is part of the Schneider Electric Acti 9 range, suggesting good compatibility with other products in that ecosystem.
Care: Maintain a clean environment around the switch. Periodically check connections for tightness (ensure power is off and locked out before inspection). Wipe the exterior with a dry or slightly damp cloth if necessary. Avoid using abrasive cleaners or solvents. Ensure the IP20 rating is maintained by keeping the enclosure it's installed in properly sealed.
