Phoenix Contact, VAL-CP-350-ST Surge Protector 350 V ac Maximum Voltage Rating 40kA Maximum Surge Current Protective

PLUGTRAB PT- IQ Intelligent and systematic surge protection plugs for the PLUGTRAB PT- IQ surge protection system. The PLUGTRAB PT- IQ protective systems has unique three stage display which indicates damaged as well as failed plugs. The three display stages are: Green - OK; Yellow - Performance limit reached and replacement recommended; Red - Overloaded and replacement required. The replacement PLUGTRAB PT-IQ Plugs are for both the direct and indirect grounding connection options.

Reduce the chance of your power system failing with this surge protector from Phoenix Contact. It's a Type 2 device that protects against defects caused by overvoltage to minimise the risk of serious equipment damage. Protective components like this one are commonly installed in power distribution systems and machine control cabinets.
For superior safety, the surge protector is able to safely discharge overvoltage from both indirect lightning strikes and switching operation. A rapid response time of ≤25ns means the device reacts almost instantly to voltage surges, to deliver optimum equipment protection. The unit clips easily onto a mounting base for fast and tool-free assembly.
As this surge protector has a robust PBT housing, you can be sure of a long service life and reduced maintenance. A UL 94V-0 rating means it's flame-retardant and unlikely to catch alight in the event of an electrical fire.

• Wide operating temperature range of -40°C to +80°C for use in harsh conditions
• Meets EN 61643-11 standards for surge protection against the indirect and direct effects of lightning or other transient overvoltage
• Withstands high maximum surge currents of up to 40kA for comprehensive protection
• IP20 rated housing is protected against human touch and objects larger than 12mm

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.
