FAQs
The PDB321-2 is designed for panel mounting with IP-20 finger-safe protection. When installing, ensure a suitable panel cutout accommodates its 3.95 in length, 3.2 in height, and 3.62 in width, and secure the unit to a sturdy panel to maintain alignment with tin-plated aluminum connectors for reliable electrical contact and long-term durability.
Yes. The block is rated for 600 Vac and 600 Vdc, with a 175 A amperage rating and SCCR of 200 kAIC. This makes it versatile for mixed AC and DC distributions within the same control cabinet, reducing the need for multiple block types.
The PDB321-2 is RoHS compliant and features IP-20 finger-safe protection. While specific third-party certifications may vary by region, Eaton provides RoHS compliance and the IP-20 safety rating as standard features, supporting safe operation in typical industrial environments.
This two-pole distribution block is ideal for control panels in machine builders and automation cabinets that require reliable high-current distribution, panel mounting, and safe operation in both AC and DC circuits. Its compact footprint and robust SCCR support broader deployment in process and machine automation.
The block’s tin-plated aluminum connectors provide corrosion resistance, reducing maintenance intervals in harsh environments. The panel-mount design simplifies installation, lowers commissioning time, and the high SCCR minimizes risk of damage during faults, contributing to lower lifecycle costs and improved uptime for automated systems.
