Special features
IP-20 Finger-safe
IP-20 finger-safe enclosure enhances operator safety by minimizing exposed conductors during routine maintenance. This safety feature lowers incident risk and simplifies lockout-tagout compliance in busy control panels. The PDB370-3 is designed for panel mounting with tin-plated aluminum connectors, enabling reliable, compact wiring within standard enclosures. High short-circuit protection is critical in motor drives and distribution networks. The PDB370-3 delivers SCCR up to 200 kAIC for #6-2 AWG and 100 kAIC for #14-2 AWG, supporting demanding fault events without derating. This translates to improved upstream protection, reduced nuisance trips, and greater system reliability in industrial settings. Three-pole configuration simplifies three-phase distribution and reduces wiring complexity. The compact panel-mount footprint and clear labeling help installers route conductors quickly, lowering assembly time and wiring errors. This is especially valuable in space-constrained control panels where efficiency directly lowers total installed cost. Tin-plated aluminum connectors provide corrosion resistance and durable contact performance in harsh environments. This improves long-term reliability and reduces maintenance costs due to connection failures. The material choice aligns with industrial expectations for rugged, low-maintenance power distribution blocks. 600 Vac and 600 Vdc ratings support mixed-voltage architectures within a single block, enabling flexible system design. The unit handles up to 310 A, supporting high-current distribution while maintaining compact form factor. Panel mounting and integrated features help meet density targets without sacrificing safety or accessibility. RoHS compliance and manufacturer certification are available on request, ensuring regulatory alignment and traceability. This helps with procurement, supplier qualification, and plant-wide standardization. When paired with Eaton's datasheet and multimedia resources, the PDB370-3 streamlines spec-to-install workflows and reduces change-management risk.

FAQs
The PDB370-3 is designed for panel mounting and uses tin-plated aluminum connectors. It supports conductor ranges from #6-2 AWG to #14-2 AWG, enabling high-current, multi-wire terminations within standard control panels. Proper mounting to a panel reduces vibration-induced wear, and using compatible lugs and fasteners ensures secure, code-compliant connections during routine maintenance.
Key specifications include a 310 A amperage rating and voltage ratings of 600 Vac and 600 Vdc. Short-circuit rating (SCCR) is up to 200 kAIC for #6-2 AWG and 100 kAIC for #14-2 AWG. These figures enable robust fault tolerance and help minimize upstream protection coordination challenges in demanding installations.
Yes. The unit is rated for both 600 Vac and 600 Vdc, enabling mixed-voltage distribution within a single block. This flexibility is advantageous for panel builders integrating AC power and DC bus sections in a compact footprint without compromising safety or reliability.
The block features IP-20 finger-safe protection and RoHS compliance. Manufacturer certifications are available on request, allowing procurement teams to confirm regulatory alignment and supplier qualifications for their specific industry requirements.
Tin-plated aluminum connectors provide corrosion resistance and durable contacts, reducing maintenance need and premature contact wear in harsh environments. The design supports long-term reliability in busy panels, lowering replacement frequency and minimizing downtime in manufacturing environments.
