FLASHTRAB Type 1 Single-pole modular lightning surge protector®

FLASHTRAB is a primary encapsulated lightning surge protector with electronic triggering, designed to protect low voltage single- or three-phase power supply for installations.
It quenches overvoltage resulting from distant impacts, or ground potential rise (GPR) or manoeuvres.
With its strong surge protection, it also quenches direct lightning strikes (e.g. installation equipped with a lightning rod or supplied by an airborne network) in accordance with IEC 61024-1 and IEC 61312-1.
Connects in parallel on the mains network and snaps onto a symmetric profile.
A wiring bridge allows several modules to be quickly mounted and bridged on the ground connection.
If a sensitive device is located at over 30 m from the core of the installation, an additional type 2 lightning protector should be connected immediately upstream of this device.

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 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.
