WJ Furse, ESP M1 Surge Suppressor Unit 280V Maximum Voltage Rating 80 kA Maximum Surge Current Mains Surge Protector

Protect your machinery from sudden voltage spikes with this robust surge suppressor from WJ Furse. The device monitors your circuit and draws excess voltage to the ground when it detects an impulse supply. Its steel housing provides reliable resistance to impact and corrosion, so you can use it in demanding environments. LED status indicators make the suppressor easy to monitor and troubleshoot where necessary. With its pre-warning feature, you can stay protected at all times, even in lightning-prone areas.

• Integrated 125A backup fuse to provide short-circuit protection

• Telecommunications industries

Yes, this surge suppressor has an IP20 (ingress protection) rating, which means that it can withstand dust and objects larger than 12mm in size.

An appliance designed to protect electrical devices from voltage spikes. Enhanced surge protectors are ideal for use on power distribution systems. To protect connected electronic equipment from transient overvoltages on the mains supply such as computers, communications and control equipment. Our surge protectors offer an advanced pre-warning so you can stay protected with repeated protection, in lightning prone environments. These products are easy to apply and have an innovative feature to disconnect safely from faulty supplies.

Very low let-through voltage between all lines (L-E, L-N, N-E)

WBX 3 (456-8112) for ESP 240 M1

Voltage surges, often referred to as spikes or transient overvoltages are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning activity and can reach up to 6000V, with current surges of up to 3000A. The maximum size of the voltage and current surges depends on the location within the buildings wiring system. BS6651:1999 Annex C which was replaced in August 2008 by BS EN 62305-4:2006 is complemented by BS EN 61643-11/12 and covers location categories and provides guidance on protection of electronic equipment. For mains power systems, Types I, II and III are used. Surge protection devices not designed to fit into these categories may only provide limited protection and the equipment they protect may suffer damage.
