Why Choose the Mersen BB1-2PPCL Phase Barrier?
The Mersen BB1-2PPCL is a durable plastic phase barrier designed to provide electrical separation between adjacent phases in multipole NH fuse-base and fuse-switch-disconnector assemblies. Suitable for NH sizes 1 and 2, this accessory helps improve insulation, installation safety and phase-to-phase separation within industrial electrical distribution equipment.
Also identified by the Mersen item number J214690, the BB1-2PPCL is intended for use with compatible Mersen NH fuse holders and switching devices. Its insulating construction creates a physical partition between two phases, helping reduce the risk of accidental contact or electrical flashover within closely mounted assemblies.
With a product length of approximately 250 mm and a height of 115 mm, the barrier is shaped for straightforward installation alongside compatible size 1 and size 2 NH components. It is supplied in packs of two, making it suitable for creating separation within a typical three-pole assembly.

Reliable Phase Isolation for NH Fuse Assemblies
Phase barriers are used within multipole electrical assemblies to create a physical insulating partition between live conductors and fuse-base contacts. This separation helps maintain suitable electrical clearances and reduces the likelihood of accidental phase-to-phase contact during installation, inspection or maintenance.
The Mersen BB1-2PPCL is specifically designed for compatible NH size 1 and size 2 equipment. When installed between adjacent poles, it supports the safe construction of compact power-distribution and circuit-protection assemblies without unnecessarily increasing panel space requirements.
Typical Applications
- Multipole NH fuse-base assemblies.
- NH fuse-switch disconnectors.
- Industrial electrical distribution boards.
- Low-voltage switchgear and control panels.
- Motor control centres.
- Power-distribution cabinets.
- OEM electrical-panel construction.
- Fuse-protection installations requiring phase separation.
