Smart. Small. Pluggable.

Powerful surge protection for plants, people, processes and the environment. 

 

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.

Benefits of M-LB-4000

Reliable Diagnostics Inside

The M-LB-4000 offers reliable self monitoring inside: The display shows status information which also can be forwarded to the control level with a fault status indication module. This allows easy maintenance and reduces operational costs.

Space-Saving Housing Design

With a width of just 6 mm, the M-LB-4000 surge protection modules provide the highest packing density and reduce installation space to a minimum. User-friendly mechanics allow operational staff to conveniently install the protection modules without any additional wiring effort.

 

Modular Design

The modular design of the M-LB-4000 system allows users to quickly exchange pluggable surge protection modules during operation—without any interruption of the signal circuit.

Loop Disconnect Feature

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.

Benchmarks in Surge Protection

Overvoltages due to lightning strikes or switching operations are one of the most common causes of electronic damage. Pluggable surge protection M-LB-4000 offers continious self-monitoring with status indication to protect you process plant.   

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.
