PEPPERL+FUCHS Surge Protector Barrier

PEPPERL+FUCHS Surge Protector Barrier

This Surge Protection Barrier limits induced transients of different origin
(e. g. lightning stroke, switching impulse, etc.). This is achieved by
diverting the transient current to ground and limiting the signal line
voltage to a safe level for the duration of the surge.

Product Details


This barrier provides 85 V line-to-line and 500 V line-to-ground clamping voltage for the protected instruments. It also protects instruments that have less than 500 V isolation-to-ground. It is installed in an available conduit or cable gland opening like those found on most process transmitters.

Note: Surge Protection Barriers must always be connected to a solid and effective ground and be at the same equipotential level as the instrument it is protecting. The ground system must comply with all applicable regulations.
