Need a surefire way of stopping power spikes in their tracks? Turn to this surge protector from Schneider Electric. As it has an integrated circuit breaker, it reliably trips connected circuits to de-energise them when current or voltage faults crop up. This shields any linked 1P+N installations from damage and helps slash the risk of electrical fires or shocks. Thanks to a broad operating temperature range between -25°C and +60°C, you can rest assured this product's a practical pick for harsh settings. The withdrawable cartridge design makes the module handy for quick changeovers whenever one needs replacing.

• Automated message lets you know when it's time to change the cartridge
• Insulated up to 1.5kV to protect against voltage surges
• Approved to resist impacts, so it's a safe bet for demanding industrial workspaces
• Works up to 2000m, making it viable for high-altitude locations

• Electrical distribution networks
• Commercial buildings
• Factories

The unit clips easily onto a standard 35mm DIN rail, so it's a breeze to install or remove without any tools.

Voltage surges, often referred to as spikes or transients are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage spikes are usually caused by lightning strikes and can reach up to 6000V, with current surges of over 3000A. The maximum size of the let-through voltage and current inrush depends on the location within the building's wiring system. BS7671: 2011 Amendment 1 Sections 443 and 534 cover risk assessment and provides guidance on protection of electronic equipment for installation engineers to follow. The fullest information on lightning and surge protection comes from the BSEN 62305 series of standards.
