Why Choose the Mersen BB1-2-3BARRIER Phase Barrier?
The Mersen BB1-2-3BARRIER is a durable plastic phase barrier for NH size 1, 2 and 3 fuse systems. Also identified by the Mersen item number P215086, this accessory is designed to provide electrical separation between two adjacent phases in compatible NH fuse bases and fuse switch disconnectors.
The barrier creates a physical insulating partition between neighbouring live components, helping maintain suitable phase-to-phase clearances within industrial switchboards and power-distribution panels. Its robust polypropylene construction makes it suitable for demanding electrical installations where reliable insulation and organised component spacing are required.
With a product length of approximately 192 mm, the BB1-2-3BARRIER is designed for straightforward integration with selected Mersen NH1, NH2 and NH3 equipment. It is supplied in packs of ten, making it suitable for switchboard manufacturing, panel-building projects and ongoing maintenance requirements.

Reliable Phase Isolation for NH Fuse Systems
Multipole NH fuse assemblies require adequate insulation between adjacent live phases. A dedicated phase barrier creates a physical partition between neighbouring fuse positions, helping reduce the risk of accidental contact, electrical flashover and phase-to-phase faults.
The Mersen BB1-2-3BARRIER is designed for compatible NH size 1, 2 and 3 fuse bases and fuse switch disconnectors. It performs an insulating and mechanical separation function and does not form part of the current-carrying circuit.
Typical Applications
- NH1, NH2 and NH3 fuse-base assemblies.
- NH fuse switch disconnectors.
- Industrial low-voltage switchboards.
- Electrical power-distribution panels.
- Motor control centres.
- Machinery and automation control cabinets.
- OEM switchgear and electrical-panel construction.
- Maintenance and replacement of phase barriers.
