Hager KDN363A Insulated Busbar 3P 63A Fork 10mm2 12 Module

The Hager KDN363A is a 3-pole phase busbar with fork connection, designed to distribute power across multiple circuit breakers within a distribution board. Rated at 63A with a 10mm² conductor connection cross-section, it accommodates up to 12 modules and is suitable for use in standard DIN-rail enclosures operating at 230-400V.

Technical specifications:

• Catalog reference: KDN363A
• Manufacturer: Hager
• Product type: 3-pole phase busbar with fork connection
• Rated current: 63A
• Number of poles: 3
• Rated operating voltage (Ue): 230 - 400V
• Impulse withstand voltage (Uimp): 4500V
• Connection cross-section (rigid conductor): 10mm²
• Connection type: Phase busbar with fork
• Number of modules: 12
• Length: 210mm
• RoHS compliant: Yes

Features and benefits:

• Fork connection type allows quick and secure attachment to circuit breaker terminals without additional tools.
• 12-module capacity supports installation of up to 12 single-pole devices on a single busbar run.
• Impulse withstand voltage of 4500V provides protection against transient overvoltages in the distribution system.
• 10mm² conductor cross-section at 63A rated current suits typical residential and light commercial load requirements.
• RoHS compliant construction meets European hazardous substance restrictions.

Applications:

• Residential distribution boards requiring 3-phase power distribution across multiple MCBs or RCBOs.
• Light commercial consumer units where a 63A, 12-module busbar covers the panel's circuit count.
• Replacement or extension of existing phase busbars in Hager-compatible enclosures rated for 230-400V systems.
• New panel builds where a fork-type busbar simplifies wiring compared to individual cable connections.
