April 24, 2019 - Pepperl+Fuchs’ M-LB-2000 system offers surge protection with a loop disconnect function for maintenance and commissioning, designed for use in applications that only require a minimal specification.
The M-LB-2000 can also be used as an alternative to terminal blocks with surge protection. The terminal blocks can be replaced by the 6.2 mm slim modules with no additional space required. The one-piece devices can be mounted on a standard DIN mounting rail, are approved for applications up to SIL 3, and are certified in accordance with ATEX and IECEx up to Zone 1. This makes the M-LB-2000 system the complement to the M-LB-5000 surge protection system - the two-part system that offers diagnostic functions.
The M-LB-5000 with condition monitoring function has patented diagnostics and uses a special algorithm to detect different overload situations that can cause the surge protection functionality to wear out.
