Stop electrical faults from disrupting your signalling system with this surge protection connector from Phoenix Contact. It works with a mounting base (768-1195) to protect up to four conductors against surges, letting your control devices send signals reliably and supporting efficient process management. With its 20kA surge protection rating, the plug withstands large power loads, so you can trust your hardware is secure. It's compatible with conductor cross-sections between 24 and 12AWG for compatibility with common industrial appliances.
The unit comes with colour-coded indicator lights on its front face, keeping you informed about the status of your surge protection with clear diagnostics. As the device draws just a 300mA current during operation, it's an energy-efficient option to suit applications with power restrictions. With low-profile dimensions of 17.7 (W), x 45 (H) x 52mm (D), the product fits neatly into busy systems.

• UL 94 V0 inflammability rating means it helps to slow the spread of fire
• Meets IEC 61643 standards to indicate protection against lightning
• Durable PA housing prevents damage to sensitive elements from impacts
• Dedicated labelling spaces for easy connection identification

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.
