Why Choose the Mersen X227927 US14PAK UltraSafe Connection Kit?
The Mersen X227927, catalogue number US14PAK, is a multi-pole connection and assembly kit designed for compatible Mersen UltraSafe™ US14 modular fuse holders. It allows individual fuse-holder poles to be mechanically linked together, helping panel builders create coordinated multi-pole assemblies for industrial electrical protection systems.
Developed for the UltraSafe US14 range, the kit is intended for fuse holders accepting 14 × 51 mm cylindrical fuse-links. It provides a practical solution where separate single-pole holders need to operate together as a two-pole, three-pole or other coordinated assembly, subject to the configuration of the compatible fuse holders.
The X227927 supports neat and efficient panel construction while maintaining the modular flexibility of the UltraSafe system. It is suitable for use with compatible fuse-holder installations rated up to 50 A and 750 V AC. As an accessory kit, it does not contain a fuse-link or provide overcurrent protection independently.

Flexible Multi-Pole Fuse-Holder Assembly
Modular fuse holders are often installed as individual poles, allowing panel builders to select the exact number of protected conductors required for an application. A connection kit mechanically links compatible poles so that they can be arranged and operated as a coordinated multi-pole unit.
The Mersen X227927 is specifically intended for the UltraSafe US14 fuse-holder family. It helps create a more organised assembly while retaining the finger-safe and modular characteristics of the compatible fuse holders. Correct fuse holders and suitably rated 14 × 51 mm fuse-links must be selected separately.
