## Summary description

Schneider Electric iSW-NA modular load break switch, rated 100A with 4 poles for 415V AC systems (model A9S70790). Designed for switching and isolating circuits in distribution boards and industrial panels, it offers secure manual operation, compact modular format for DIN-rail mounting and is suitable for load break and maintenance isolation in commercial and residential electrical installations.

## Long description

Schneider Electric iSW-NA modular load break switch, rated 100 A in a 4-pole configuration for 415 V AC systems, is built for manual switching and safe isolation in distribution boards and industrial control panels. The compact modular format fits on standard DIN-rail assemblies and provides reliable load breaking and maintenance isolation for both commercial and residential electrical installations. The device is intended for use where a straightforward, mechanical means of disconnecting circuits is required, without relying on control circuitry.
Advantages
The iSW-NA switch offers a compact design that saves panel space while delivering a clear mechanical indication of contact position. Its 4-pole construction enables simultaneous isolation of all phases and the neutral in three-phase systems up to 415 V AC. Manual operation ensures simple, immediate control for maintenance and emergency isolation tasks. The modular housing and DIN-rail compatibility simplify installation and replacement in standard distribution enclosures.
Suitable for
Isolation and switching of three-phase loads in commercial and light-industrial panels
Maintenance isolation in residential and multi-dwelling electrical distribution boards
Use as a local disconnect for motors, heating circuits, and auxiliary circuits
Retrofit or new installations where DIN-rail modular components are required
Key specifications
Rated operational current: 100 A
Number of poles: 4 (three phases plus neutral)
Rated voltage: 415 V AC (three-phase systems)
Mounting: DIN-rail compatible modular housing
Operation type: Manual load break switch with visible contact position
Intended use: Switching and isolation for distribution and control panels
How to use
Mount the modular switch on a standard DIN-rail inside the distribution board, ensuring adequate space for wiring and heat dissipation. Connect incoming and outgoing conductors to the designated terminals following local wiring regulations and the panel wiring diagram. Operate the toggle or handle to open or close the contacts; verify the visible position indicator to confirm isolation before performing maintenance. Ensure the switch is suitably rated for the connected load and that overcurrent protection devices are coordinated with the switch's use.
Usage recommendations
Install and maintain the switch in accordance with applicable electrical standards and local regulations. Verify compatibility with upstream protection devices and ensure terminals are tightened to the manufacturer’s recommended torque. Use the device only within its rated current and voltage limits and perform periodic inspections to detect wear, corrosion, or loose connections.
