Why Choose the Mersen H302894 Four-Pole Busbar End Cap?
The Mersen H302894 is a purpose-designed four-pole busbar end cap used to protect the exposed ends of compatible wiring bars installed with DIN-mounted fuse switch disconnectors and modular electrical devices. Also identified by catalogue number 02904.000000, it provides a neat and secure termination for multi-pole busbar assemblies.
Fitting an appropriate end cap helps provide optimum protection against accidental contact with conductive busbar ends. It also reduces the risk of electrical arcing at the termination point, supporting safer and more dependable operation within electrical distribution boards, control panels and industrial enclosures.
The H302894 is designed for four-pole wiring-bar configurations and is suitable for use with compatible Mersen fork-design busbar systems. Its compact, lightweight construction allows straightforward installation while maintaining an organised and professional panel layout.

Reliable Protection for Wiring-Bar Terminations
Wiring bars provide an efficient method of distributing power between multiple modular electrical devices. However, the cut or exposed end of a multi-pole bar must be appropriately protected to reduce the possibility of accidental contact and electrical arcing.
The Mersen H302894 provides this protection for compatible four-pole wiring bars. When correctly installed, it completes the busbar assembly and helps maintain a safer, cleaner and more professional electrical panel installation.
Typical Applications
Four-pole wiring-bar assemblies.
DIN fuse switch disconnector systems.
Electrical distribution boards.
Industrial control panels and cabinets.
Commercial electrical enclosures.
Machine-building and automation panels.
Multi-pole modular power-distribution systems.
