Overview
The Bussmann 16323-3 is a barrier terminal power distribution block engineered for reliable power distribution in industrial automation and control systems. Part of Bussmann’s Magnum series, this 3-pole block delivers 310 amps at 600VAC/VDC with a 100 kA short-circuit current rating (SCCR). The tin-plated aluminum connector and molded thermoplastic base ensure dependable performance in demanding electrical environments.
Key Features
- UL Recognized to UL 1059 and rated for UL 508A industrial control panels
- 3-pole configuration with single primary and multiple secondary connections (1 primary, 6 secondary per pole)
- High current capacity: 310A at 600VAC/VDC with 100 kA SCCR
- Flexible wire acceptance: 6 AWG to 350 kcmil primary, 14 to 4 AWG secondary (copper/aluminum)
- Dual wire port capability for increased connection density when using matched wire sizes
- Optional safety covers available separately (CPDB-3) for enhanced personnel protection
Technical Specifications
The block features a box lug connection type optimized for panel-mount applications. Tin-plated aluminum connectors provide corrosion resistance, while the UL 94 V0 flammability-rated thermoplastic base meets stringent safety standards for industrial control environments.
