Hager KDN380A Insulated Busbar 3P 80A Fork 16mm2 12 Module

The Hager KDN380A is a 3-pole phase busbar with fork connection, designed to distribute power simultaneously across circuit breakers and modular devices in distribution boards. Rated at 80 A and suitable for 230-400 V systems, it spans 12 module positions and accepts a 16 mm² rigid conductor for a direct, tool-assisted connection into device terminals.

Technical specifications:

• Catalog reference: KDN380A
• Manufacturer: Hager
• Product type: 3-pole phase busbar with fork connection
• Rated current (In): 80 A
• Rated operating voltage (Ue): 230 - 400 V
• Impulse withstand voltage (Uimp): 4500 V
• Number of poles: 3
• Number of modules: 12
• Length: 210 mm
• Conductor cross-section (rigid conductor): 16 mm²
• Connection type: Fork connection busbar (Phasenschiene mit Gabel)
• RoHS compliant: Yes

Features and benefits:

• Fork connection design inserts directly into MCB, RCBO, and RCCB terminals across all 3 poles simultaneously, eliminating individual feed wires.
• 12-module coverage in a single piece reduces installation time compared to individually wired breakers.
• 80 A current rating suits standard residential and light commercial 3-phase panel configurations.
• 4500 V impulse withstand voltage (Uimp) provides protection against transient overvoltages in the distribution board.
• RoHS compliant construction meets European environmental requirements for restricted substances.

Applications:

• 3-phase residential distribution boards requiring simultaneous power feed to multiple MCBs or RCCBs.
• Commercial panel boards using modular DIN rail devices in 12-module rows.
• Industrial control cabinets where a compact 3-pole busbar replaces multiple individual conductors.
• Retrofit installations in existing enclosures operating at 230/400 V where space and wiring simplicity are priorities.
