Why Choose the Mersen BB3NDISCON NH3 Disconnectable Neutral Base?
The Mersen BB3NDISCON is a robust NH3 disconnectable neutral base designed for use alongside NH fuse bases in low-voltage power distribution assemblies. Also identified by the Mersen catalogue reference P217754, it provides a dedicated neutral-pole connection that can be safely isolated during inspection, testing and maintenance.
This component is intended for professional installation within industrial switchboards, distribution panels and electrical control equipment. Its disconnectable design gives engineers convenient access to the neutral conductor without requiring permanent removal of the connected cabling, helping simplify commissioning and maintenance procedures.
Designed to correspond with NH size 3 fusegear, the BB3NDISCON supports the construction of coordinated multi-pole distribution arrangements. Its durable construction and secure connection system make it suitable for demanding industrial and commercial electrical installations where reliable neutral isolation is required.

Reliable Neutral Isolation for Electrical Distribution
A disconnectable neutral base provides a controlled method of opening the neutral conductor within a distribution assembly. This can assist electrical engineers when carrying out insulation testing, fault finding, commissioning or planned maintenance on outgoing circuits.
The Mersen BB3NDISCON is designed to form part of a coordinated NH fusegear installation. Its NH3-compatible construction helps panel builders create consistent phase and neutral arrangements within industrial switchboards while maintaining convenient access for future servicing.
Typical Applications
- Industrial low-voltage switchboards.
- Electrical distribution panels.
- Power distribution units.
- Motor control centres.
- Commercial building distribution systems.
- OEM electrical control equipment.
- Panel-building and switchgear assemblies.

Frequently Asked Questions
What is the Mersen BB3NDISCON used for?
The BB3NDISCON provides a disconnectable neutral connection within an NH fusegear or low-voltage power distribution assembly.
Is the BB3NDISCON a fuse holder?
No. It is a neutral-pole base rather than a fused phase-pole holder. It is designed to complement the associated NH fuse bases in a distribution assembly.
Which NH fusegear size is it designed to match?
The BB3NDISCON is designed to correspond with NH size 3 fusegear.
Why is the neutral connection disconnectable?
A disconnectable neutral allows the conductor to be isolated during electrical testing, commissioning, fault finding and maintenance procedures.
What is the Mersen catalogue number for this product?
The Mersen catalogue number is P217754, while BB3NDISCON is used as the alternative product reference.
