Eaton PDB220-3 Power distribution block - IP-20 Finger-safe
Part Number: PDB220-3
Quick Summary
The Eaton PDB220-3 power distribution block is a compact panel-mount device that safely distributes power up to 175 A in industrial control panels. Engineers often grapple with safe, accessible distribution within tight control enclosures, and the IP-20 finger-safe design alongside straightforward panel mounting addresses that challenge. While CE or SIL certifications aren’t listed, the RoHS compliance, IP rating, and SCCR ratings—200 kAIC (#12-4 AWG) and 100 kAIC (#14-4 AWG)—provide critical safety and reliability context. This block complements standard panel hardware and adds a reliable, scalable option for power management and distribution applications, supporting efficient installations and easier maintenance.

Eaton Specification Sheet - PDB220-3
Three-pole construction with a 175 A rating enables centralized distribution from a single source, reducing wiring complexity and improving fault isolation in control panels. This translates to higher system uptime and simpler protection coordination for panel-mounted power circuits, especially in compact cabinets used for drives and automation controllers. IP-20 finger-safe protection paired with RoHS compliance enhances operator safety and environmental responsibility. Tin-plated aluminum connectors resist corrosion in harsh industrial environments, lowering maintenance frequency and improving long-term reliability in outdoor or damp enclosures. SCCR ratings of 200 kAIC for #12-4 AWG and 100 kAIC for #14-4 AWG provide robust short-circuit margins that reduce upstream device requirements, simplifying panel fabrication and commissioning. Voltage rating of 600 Vac and 600 Vdc enables mixed AC/DC panel configurations, reducing the need for multiple blocks and simplifying inventory. With a panel-mount footprint and tin-plated connectors, installation is straightforward, and future expansion can be planned without changing the distribution block. Compact form factor—2.9 in deep, 2.12 in high, and 4.25 in wide—along with a lightweight 0.84 lb weight aids cabinet fill calculations and commissioning speed, enabling repeatable, scalable deployments across multiple enclosures.

FAQs
Yes. The PDB220-3 is designed for panel mounting with a three-pole configuration and includes tin-plated aluminum connectors for internal wiring. Its compact dimensions—2.9 in depth, 2.12 in height, and 4.25 in width—fit typical control panels, facilitating straightforward wiring harness integration. Follow manufacturer torque specs and panel cutout recommendations to ensure reliable, vibration-resistant connections.
The PDB220-3 offers SCCR ratings of 200 kAIC for #12-4 AWG conductors and 100 kAIC for #14-4 AWG conductors, supporting high short-circuit withstand capability in panel environments. It is rated for 600 Vac and 600 Vdc, enabling use in mixed AC/DC control panels. These specifications help simplify protection schemes and improve system reliability.
This three-pole distribution block is well suited for panel power distribution in control cabinets, motor drives, and industrial automation enclosures. Its high amperage rating and robust SCCR make it ideal where centralized distribution, clear fault isolation, and compact footprint are required. The tin-plated aluminum connectors promote long-term durability in challenging plant environments.
The block is IP-20 finger-safe and RoHS compliant, underscoring safety and environmental responsibility in many regions. Specific CE or SIL certifications are not listed in the provided data; however, the IP rating and RoHS status, along with high SCCR, provide meaningful safety and regulatory context for most industrial applications while manufacturers can supply additional certifications on request.
By delivering a compact, panel-ready 175 A distribution solution with corrosion-resistant tin-plated connectors, the PDB220-3 reduces wiring complexity and maintenance frequency. Its durable construction lowers replacement costs and simplifies stock management with a single, high-capacity block for multiple feeders. The predictable form factor also speeds installation and commissioning, delivering faster ROI in new builds and retrofits.
