Why Choose the Mersen K302873E Insulated Pin Busbar?
The Mersen K302873E is a robust three-pole insulated pin busbar designed to distribute electrical power efficiently across compatible DIN-mounted fuse devices and modular panel equipment. Also identified by catalogue number 22963.003000, it provides a convenient and organised alternative to wiring each device individually.
Featuring a 16 mm² conductor cross-section and an 80 A current rating, the K302873E is engineered for reliable power distribution in industrial and commercial electrical installations. Its insulated construction helps protect the conductive sections, while the pin connection design makes it suitable for compatible devices with box, frame or two-screw clamp terminals.
The busbar has an overall length of 1045 mm, a 27 mm pitch and 39 modular spaces, providing connections for up to 13 three-phase circuits. Rated for operation at up to 480 V AC or DC, it is suitable for demanding distribution boards, machinery panels and modular fuse-protection assemblies.

Efficient Power Distribution for Modular Devices
Pin busbars such as the Mersen K302873E distribute an incoming electrical supply across multiple compatible devices through a common conductive assembly. This method reduces the number of separate cables and terminal connections required, helping installers create cleaner and more consistent electrical panels.
The K302873E is intended for compatible modular panel-mounted devices manufactured in accordance with DIN 43880. Its pin connections are particularly suitable for devices with box terminals, frame terminals or two-screw clamps. An appropriate incoming terminal and protective end caps should be used to complete the installation safely.
Typical Applications
- DIN-mounted fuse switch disconnector systems.
- D0 and cylindrical fuse-device installations.
- Three-phase electrical distribution boards.
- Industrial control panels and machinery cabinets.
- Commercial power-distribution equipment.
- OEM machine-building applications.
- Multi-circuit modular electrical assemblies.
