PRODUCTS DETAIL
Product Picture
Features
● Provides reliable lightning protection for electrical circuits across diverse
industrial applications.
● Ensures the highest-level defense for sensitive signals in acquisition,
transmission, and communication.
● Ultra-compact modules allow dense installation and protect mixed 2- or 3-wire
systems simultaneously.
● Perfect for RTDS, THCS, 4–20 mA loops, and other telemetry signal protection.
