Why Choose the ABB ML35 NH Switch Expansion Module?
The ABB ML35, order code 2CPX041369R9999, is a mounted NH fuse switch disconnector expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides the mechanical and busbar infrastructure required to integrate NH fuse switch disconnectors into higher-current commercial and industrial sub-distribution cabinets.
The ML35 is supplied unequipped for the installation of up to 12 NH1–NH3 fuse switch disconnectors and is compatible with ABB SlimLine XR and Jean Müller Sasil equipment. It uses a 185 mm busbar system with three horizontally arranged copper busbars and ABB ZX523 busbar holders, providing a robust platform for fused switching and isolation applications.
With a module height of 5 GU / 750 mm, a panel width of 3 PW / 750 mm, 180 space units and a usable width of 600 mm, the ML35 provides substantial capacity for larger distribution assemblies. The busbar system supports a maximum rated current of 850 A, while the module is designed for installation in cabinets from 625 mm depth.

Reliable NH Fused Power Distribution
NH fuse switch disconnectors combine high-capacity fuse protection with switching and isolation functions for electrical distribution circuits. The ABB ML35 provides a 185 mm 3-pole busbar system and mounting infrastructure for up to 12 NH1–NH3 fuse switch disconnectors, allowing panel builders to create organised and serviceable fused outgoing circuits for demanding distribution applications.
The ML35 is supplied unequipped so that suitable ABB SlimLine XR or Jean Müller Sasil fuse switch disconnectors can be selected according to the installation requirements. Its horizontally arranged busbar system uses ZX523 holders and accommodates three copper rails, which must be ordered separately, while its 850 A maximum rated current supports substantial commercial and industrial power distribution systems.
Typical Applications
- Commercial and industrial sub-distribution boards.
- ABB CombiLine electrical cabinet assemblies.
- NH1–NH3 fused outgoing circuits.
- Higher-current electrical power distribution systems.
- Industrial switchgear and distribution cabinets.
- Panel building and modular power distribution installations.
