FAQs
The 16321-1 is a single-pole power distribution block with a compact footprint (5.5 in × 3.5 in × 2.5 in) and a weight of about 0.57 lb, designed for use in Eaton Bussmann series assemblies. It provides a straightforward installation path with tin-plated aluminum connectors and a molded thermoplastic base, compatible with common control cabinet layouts and standard panel mounting schemes.
The 16321-1 is rated for 175 A with a voltage rating of 600 Vac and 600 Vdc, and a short-circuit rating (SCCR) of 200 kAIC. This combination supports high-current distribution to motors, drives, and other heavy-load devices in control panels, while maintaining fault tolerance and safe clearance within typical automation enclosures.
Yes. The 16321-1’s 175 A rating, 600 Vac/600 Vdc voltage capability, and 200 kAIC SCCR make it well-suited for motor control and power distribution tasks in industrial automation. Its robust connectors and thermoplastic body help withstand vibration and temperature variations common in motor-driven applications, while keeping wiring organized and accessible for service.
The 16321-1 is RoHS compliant, supporting regulatory requirements for restricted substances. Certifications beyond RoHS are available from the manufacturer upon request. For procurement audits or design verifications, confirm current certification documents with Eaton or authorized distributors to ensure alignment with your quality and safety programs.
Maintenance benefits come from its robust build, corrosion-resistant tin-plated connectors, and a compact footprint that reduces wiring complexity. ROI stems from improved panel reliability, easier installation, and a lower risk of fault-induced downtime due to the high SCCR rating. The block’s traceability and RoHS compliance also simplify compliance checks and part sourcing over the equipment lifecycle.
