WJ Furse Surge Suppressor Unit, 280V Maximum Voltage Rating, 6.25kA Maximum Impulse Current - ESP M1 Series - 7TCA085460R0115 ESP 415M1R
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.
Features & Benefits
• Integrated 125A backup fuse to provide short-circuit protection
• Maximum impulse current rating of 6.25kA for high-powered applications
• Wide operating temperature range of -40°C to +80°C for use in harsh environments
• Light weight of 1kg makes it easy to handle
Applications
• Telecommunications industries
• Water and sewage treatment plants
• Heating and air conditioning systems
Is this surge suppressor resistant to dust?
Yes, this surge suppressor has an IP20 (ingress protection) rating, which means that it can withstand dust and objects larger than 12mm in size.
Enhanced surge protector
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)
LED status indication with pre-failure warning
Remote indication through volt-free contact
Robust steel housing
Neutral to Earth voltage warning

Transient Voltage Suppressors (Modules,Industrial)
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.
Approvals
For part ESP 240 M1 (456-8112) the Network Rail approval applies – PA05/01832. NRS PADS ref: 086/047149
