FAQs
Install the 16376-3 using standard panel mounting practices for three-pole blocks. Ensure mounting hardware provides secure mechanically-sound contact with the molded thermoplastic base, and route conductors to the tin-plated aluminum connectors to maintain low contact resistance and reduce thermal buildup. Verify 600 Vac/600 Vdc ratings are compatible with your system voltages and use appropriate strain relief on incoming/outgoing cables.
Key ratings include 420 A amperage, 600 Vac/600 Vdc voltage rating, and SCCR of 10 kAIC, supporting fault current with robust protection. The unit is RoHS compliant, aiding regulatory adherence. Its three-pole configuration supports organized, safe distribution in multi-phase systems, while the molded thermoplastic base and tin-plated aluminum connectors contribute to reliable conductivity and durability.
Yes. The three-pole design is optimized for distributing power in three-phase configurations common to industrial automation. With its high current rating and SCCR, it is suitable for panel-based power distribution where reliable fault current handling and compact footprint are important. Confirm your system’s voltage and ampacity align with the 420 A/600 Vac-600 Vdc specification before integration.
The 16376-3 is RoHS compliant, supporting environmental and regulatory requirements. Its electrical ratings (600 Vac/600 Vdc and 10 kAIC SCCR) reflect safety and performance compliance for demanding panel environments. No CE or SIL certification details are listed in the provided data, so verify project-specific certification needs with Eaton for your exact region.
The 16376-3 combines high current capability with a compact, durable design, reducing the need for multiple components and simplifying panel layouts. Its corrosion-resistant connectors and thermoplastic base help extend service life in demanding environments, lowering maintenance frequency. RoHS compliance also mitigates regulatory risk, contributing to total cost of ownership reductions over time.
