Special surge and overvoltage arrester For DM-24&DM-48 SECURE
Special surge and overvoltage arrester For DM-24&DM-48 SECURE
Product Code : DM-24&DM-48 SECURE
Product Description

Surge Arresters

DM-PROFIBUS 5 V

DM-PROFIBUS 24 V 

Combination of coarse and fine surge protection for the PROFIBUS industrial bus-bar system.

Designed to protect line and communication interfaces of the PROFIBUS industrial bus-bar system. Longitudinal overvoltage (core – earth) is prevented by coarse surge protection. Lateral overvoltage (core – core) is prevented by a two-level combination of coarse and fine surge protection. Also, cable shielding is protected.
