Why Choose the Mersen W210308 CMS810BB3F4 Wiring Bar?
The Mersen W210308, also identified by catalogue reference CMS810BB3F4, is a purpose-designed three-phase wiring bar for modular fuse holders. It provides a convenient and organised method of distributing a common electrical supply across multiple compatible Mersen fuse holder assemblies while reducing the need for individual linking conductors.
Configured for four three-pole fuse holder positions, the W210308 is designed for compatible size 8 and size 10 Modulostar® fuse holders. Its rigid busbar construction helps create secure and consistent electrical connections, making it suitable for repetitive panel layouts and grouped three-phase protection circuits.
With approximate dimensions of 215 × 30 × 15 mm, the CMS810BB3F4 provides a compact solution for industrial control panels, machinery and electrical distribution assemblies. By replacing multiple jumper wires with a single purpose-built wiring bar, it can help reduce installation time, improve panel organisation and simplify future maintenance.
