The Mersen D223517, also identified by catalogue number US273IRING, is a robust three-pole UltraSafe™ modular fuse holder designed for 27 × 60 mm cylindrical fuse links. Part of the Mersen Modulostar® CMS27 / UltraSafe™ US27 range, it provides reliable overcurrent protection support for demanding industrial power conversion, automation and electrical distribution systems.
Designed for circuits operating at up to 800 V AC or DC, the D223517 combines a finger-safe IP20 construction with a visual blown-fuse indicator. Its modular format helps simplify fuse replacement and routine maintenance while reducing the risk of accidental contact with live components.
The three-pole configuration is suitable for three-phase electrical systems, while the ring-lug terminal arrangement provides a secure electrical connection in industrial installations. DIN rail compatibility makes the fuse holder straightforward to integrate into control panels, switchboards, inverter systems and power distribution assemblies.
The Mersen D223517 securely houses compatible 27 × 60 mm fuse links used to protect electrical equipment against damaging overcurrent and short-circuit conditions. Its 800 V AC/DC rating makes it particularly well suited to industrial power conversion and semiconductor protection systems.
The finger-safe modular design helps improve operator protection during fuse inspection and replacement. An integrated visual indicator allows maintenance personnel to identify an operated fuse more quickly, helping reduce fault-finding time and equipment downtime.
