Product Details

VALVETRAB® Pluggable single-pole modular lightning surge protector

VALVETRAB is a mid-capacity lightning and surge protected designed to protect the low voltage single- or three-phase power supply of your installations.
With its strong surge protection, it quenches overvoltage resulting from distant impacts or resulting phenomena.
Its pluggable design allows for easy maintenance (surge protector plug combined with a base for electrical connection).
Disconnection feature provides continuity of electrical power supply.
Features a mechanical indicator which provides a status (operational or out of order) at all times and changeover contacts for alarm reports.
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.

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.
