Need to shield your electronics from unplanned voltage spikes? Put this surge protector from Phoenix Contact on defence. If the energy in your system exceeds 30V DC or 21V AC, the device sends excess electricity to the ground rather than your electrical circuit. This prevents breakdowns and dangerous incidents, keeping people and equipment safe.
Thanks to a wide operating temperature range between -40°C and +85°C, this product is well-suited for use in harsh work areas. Its small size of 105.8 (H) x 6.2 (W) x 100mm (D) doesn't add bulk to your DIN rail. Units like this one play a key role in protecting control systems, safety interlock circuits and telecommunications equipment.

• Low rated current of 600mA at +56°C assures you it's an energy-saving component
• PBT housing is impact-resistant to protect it from accidental knocks
• Broad operating humidity range between 5 and 95% RH lets you use it in areas where water vapour is likely
• IP20 rating indicates it's touch-proof against fingers and small tools and wires larger than 12mm
• Compatible with DIN-rail mounting to set up is simple and speedy

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.
