Eaton, MA15 Surge Suppressor Unit 280V dc Maximum Voltage Rating 12 kA Maximum Surge Current 1 Phase

Install this surge suppressor unit from Eaton's MTL range to protect your electronic equipment and computer networks. It's a safety device that filters out and cleans industrial noise and voltage spikes caused by events such as lightning strikes, switching devices and power factor correction circuits. The casing is made from polyamide, which is hardwearing and resistant to abrasion, so it's a suitable choice in industrial settings. You can use this surge suppressor with applications including media control panels, gaming consoles and servers.

• DIN rail mounting capability for easy installation and maintenance

A surge suppressor is activated when a system's voltage exceeds a pre-set threshold. It blocks excess voltage or diverts it to the ground to prevent damage to equipment.

This device can handle a maximum surge current of 18kA (kiloampere).

MA15 series of surge protective devices from Eaton MTL Crouse-Hinds protect electronic equipment and computer networks against "noise pollution". The MA15 units clean the effects of industrial noise and surges that may be caused by lightning strikes, switching devices and power factor correction circuits. Suitable for AC or DC application, MA15 surge protector units reduce both electromagnetic emissions and the susceptibility of the associated electrical equipment to emissions from other sources.

• 12kA surge protection and RFI filtering

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.
