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. In process engineering plants such as refineries with exposed building parts or extensive water management systems, 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.

Based on more than 20 years of experience, Pepperl+Fuchs has acquired significant know-how in surge protection. M-LB-4000 offers reliable diagnostics, easy handling and a space saving housing design.

Modular Design

The two-part system consists of a base module and a protection module. The latter contains the entire protection function. This modularity allows simple and convenient installation and maintenance. The base modules are mounted onto a standard 35 mm DIN-rail, while the protection modules can be plugged effortlessly into the base modules. This means that the M-LB-4000 does not require any tools for installation, and also enables devices to be replaced during operation without disrupting the existing wiring. While the base module remains in the mounting position, the protection module can be easily removed and replaced. An interruption of the signal circuit is avoided by the innovative mechanics in the base module.
