Eaton 16321-2 Power distribution block - SCCR 100 kAIC

The 16321-2 delivers 175 A across a two-pole configuration for both 600 Vac and 600 Vdc systems, supporting high-load distribution in compact form. This high-current capability reduces the number of blocks needed on a panel, simplifies wiring diagrams, and improves long-term reliability in demanding environments. In automation cabinets and motor control centers, the two-pole design supports streamlined layouts and easier future expansion. Equipped with an SCCR rating of 100 kAIC, the block offers robust fault protection that aligns with critical safety standards. This enables operation in high-energy environments such as machine centers and line-side feeders without compromising personnel safety. Designers can proceed with confidence during panel upgrades and fault-condition testing, knowing the protection margin meets industry expectations. The molded thermoplastic base paired with a tin-plated aluminum connector delivers durable insulation, stable contact surfaces, and improved thermal performance. This combination also enhances vibration resistance and corrosion resistance in harsh industrial environments, extending service life between maintenance cycles. From control panels to switchgear interiors, the construction supports reliable wiring, reduces hot spots, and improves overall efficiency. RoHS compliance (factory confirmation) ensures regulatory alignment across global supply chains and audit readiness. The compact footprint—6.5 in by 4.25 in by 3.75 in and about 0.94 lb—facilitates easy mounting in crowded panels. Installers benefit from predictable installation times, reduced wiring errors, and straightforward future upgrades without sacrificing performance. Designed for Eaton Bussmann series ecosystems, the 16321-2 integrates with existing catalogs and installation practices to minimize retrofit risk. Its two-pole configuration, black molded housing, and straightforward terminations support rapid replacements and predictable performance. Field teams benefit from consistent terminology, traceable part numbers, and a proven safety profile when upgrading or expanding power distribution blocks. In summary, the 16321-2 delivers high current, robust protection, and a compatible form factor for modern industrial panels. From motor starters to control enclosures, its 600 Vac/600 Vdc rating and 100 kAIC SCCR support reliability and compliance. Equip your installations with Eaton Bussmann power distribution blocks to simplify procurement and drive uptime.
