FAQs

The DK 7856.170 is designed for upstream busbar protection with a Wago X-Com adaptor for each 3-phase infeed. Installation involves mounting the adaptor per infeed, connecting the three-phase feeders, and ensuring proper secure contacts according to the Wago X-Com interface guidelines. Retrofit projects benefit from its modular design and clear documentation, enabling faster integration with minimal downtime.
Each infeed supports 3-phase infeed protection with a maximum rated current of 16 A per infeed. The unit is designed for three-phase applications, providing per-infeed protection to isolate faults quickly and protect busbar assemblies from overvoltage events.
Industries relying on reliable power distribution and minimal downtime, such as manufacturing, automation, and plant engineering, benefit from this module. Its retrofit-readiness and Wago X-Com compatibility make it ideal for upgrading existing panels, protecting critical feeders, and maintaining continuous operations in high-demand environments.
The DK 7856.170 uses ETIM 9 EC000942 and ECLASS 8.0 27130806 classifications, supporting consistent product categorization and supplier comparisons. While specific CE or IP ratings are not listed in the provided data, these classifications help buyers align with internal data norms and procurement systems for technical compatibility.
By providing targeted, retrofittable protection for each 3-phase infeed, the module reduces fault propagation and equipment damage, leading to lower maintenance costs and shorter unplanned downtime. The adaptor-per-infeed approach enables scalable protection as facilities expand, supporting a favorable ROI through longer component life and faster fault clearance.
