Intelligent Surge Protection M-LB-5000

Power Surge—The No. 1 Underestimated Cause of Damage

Overvoltages due to lightning strikes or switching operations are one of the most common causes of electronic damage. The process industry is vulnerable, as these surge events can cause devastating damage: from fires, damage to or destruction of expensive components and machines, to breakdown of complete automation systems—not including risks to personnel. That’s why surge protection concepts are crucial to have in your plant!

Based on 20 years of experience, Pepperl+Fuchs has acquired significant engineering know-how in surge protection. Combined with our expertise in explosion protection, analog technology, and interface modules, we developed the 6.2 mm pluggable surge protection system M-LB-5000, which offers much more than the pure protection function. Achieve a new level of reliability and performance in your plant!

Facts+Figures

Worldwide, there are about 40 to 50 lightning strikes every second, or nearly 1.4 billion strikes per year.
Lightning often strikes the same place repeatedly. The Empire State Building is hit an average of 23 times each year.
Lightning can cause dangerously high potential differences up to 2 km away from its impact point.
Lightning costs more than $1 billion in insured losses each year!
Lightning is ultrahot! A strike can heat the air around it to temperatures five times hotter than the sun’s surface.

Use Cases—Benchmarks in Surge Protection

The surge protection system M-LB-5000 reliably protects high-value components and plant assets from overvoltage and surge currents. For the first time, the module offers a unique combination of diagnostics and modularity within a narrow housing design of only 6.2 mm wide. In this video, you will see how the new system facilitates surge protection while ensuring greater efficiency, flexibility, and maximum availability to your process plant assets.

The Easiest Way to Protect Plant Assets

Checking health of surge protection module

The protection module's traffic light display shows status information and is easy to read and understand. Using the Power Rail, status information can be forwarded to the control level. Planning and maintenance personnel can check the health of the surge protection module at any time—no additional tools are needed. Entering the plant or switch cabinet is not necessary.

Exchanging modules during operation

The new surge protection system M-LB-5000 includes a base module and a pluggable protection module. This allows users to easily exchange modules during operation. If the protection module is removed and re-inserted with 180° rotation, the signal circuit is interrupted by the integrated disconnect function. This loop disconnect feature allows isolation testing as well as loop monitoring during commissioning.

Upgrading existing equipment

When upgrading existing equipment, the compact housing design allows easy and space-neutral replacement of marshalling terminals with surge components. User-friendly mechanics allow operational staff to conveniently install the modules without any additional wiring effort.
