Description
The Schneider Electric SPD 40KA 350V 1P+N (A9L40500) is a Type 2 surge protection device from the Acti9 iPRD40 range. It protects single-phase distribution boards, control panels and sensitive equipment from lightning and switching surges. Because one surge can destroy a PLC, VFD, UPS or meter in a fraction of a second, a 40kA SPD at the board is cheap insurance for any factory, office or home.
Why choose the A9L40500 SPD 40KA 350V 1P+N
- High discharge capacity: 40kA Imax and 15kA In (8/20 µs) per pole, so it handles strong surges common during the monsoon season in Bangladesh.
- Low protection level: Up below 1.4kV keeps the let-through voltage safe for electronics.
- Plug-in cartridges: a damaged cartridge can be replaced without removing the base or rewiring the board.
- Compact DIN-rail size: only 36mm (2 modules) wide, so it fits standard Acti9 and other modular boards.
- Works with TT and TN-S earthing, the systems used in most Bangladeshi LT installations.
