DEHN 920300 parte base para módulo de proteção contra sobretensões BLITZDUCTOR BXT, 1 polo, montagem em calha DIN, vermelho

In industrial control cabinets, unprotected signal lines are a common entry point for transient overvoltages caused by lightning strikes or switching operations. The DEHN 920300 base part provides the essential mounting and connection foundation for BLITZDUCTOR BXT series surge protection modules, enabling a modular and serviceable protection concept for measurement and control circuits.

Who is it for

This base element is intended for panel builders, system integrators, and maintenance technicians who need a reliable, DIN-rail-mountable base for plug-in surge protective devices. It is suitable for use in industrial environments, building automation, and process control where space is limited and uptime is critical.
