For installation convenience the SPM series allows the selection and configuration of any number of modules to suit individual applications, or complete assemblies of the most popular configurations.Applications include: LV switchboards; Sub distribution boards; Generator sets; Mobile telecommunications; Windfarms; PV Systems; Railways Features1, 2, 3 or 4 modular DIN rail mount connection bases.40kA MOV plug-in protection modules.Neutral to earth plug-in modules,Meets the requirements of BS EN62305-4:2006 (which replaced BS6651:1999 Annex C in August 2008) and BS EN61643-11/12 – Type II, Class IITested to IEEE C62.41BS6651:1999 Annex C location category BComplete assemblies of the most popular configurationsHot working replaceable plug-in modulesThermal and current overload fusingProtection status indication, Remote status indication option BenefitsProtection of expensive power assetsSingle and three phase optionsRemote monitoring into building management or SCADA systemsNuisance tripping avoidance of RCD’sSimple installationMaintenance freeSuitable for new or retrofit applications Surge Protection Devices, SPDs (DIN-rail) 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 surges are usually caused by lightning and can reach up to 6000V, with current surges of over 3000A. The maximum size of the voltage and current surges 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. |
