Flagship Electrical Architecture for 5-Wire Dual-Source Systems
The Switch Terminal 400 Frame 10x16 represents the highest level of heavy-duty switch terminal technology. It is custom-developed for complex three-phase five-wire electrical systems that require a dedicated neutral track and a protective grounding network (3P+N+PE). This 10-pole block combines two complete 5-wire entries-Feed A (L1/L2/L3/N/PE) and Feed B (L1'/L2'/L3'/N'/PE)-into one housing. It is engineered for highly critical environments, such as medical IT isolation grids, semiconductor cleanrooms, and high-specification international industrial projects.
Ultimate Dielectric Isolation Boundaries & Wire Gauge Capacity
≥15mm Extreme Separation Between Feeds: Designed with massive physical internal partitions that establish a clear electrical isolation distance of ≥15mm between Feed A and Feed B, which easily withstands high fault currents and blocks cross-source failures.
≥8mm Internal Phase, Neutral, and Earth Separation: Inside each feed, all lines are separated by a clearance distance of ≥8mm, completely suppressing short circuits, air arcing, and electrical interference under transient overvoltages.
Full-Capacity Grounding and Current Routing: Accommodates copper wire sizes from 10mm² to 16mm² per pole across all ten terminals, ensuring that the neutral and protective earth (PE) paths match the full 400A system capacity (200A per feed).

Maximum Volumetric Space Reclamation & Workforce Savings
60% Reclamation of Panel Real Estate: By replacing two separate 5-pole terminal blocks with this single integrated unit, it reclaims approximately 60% of vertical and horizontal panel space, leaving a clean, open layout inside complex ATS cabinet assemblies.
Streamlined Field Connection Efficiency: The pre-configured 10-way layout eliminates messy external jumper bars, making installation simple and cutting on-site wiring and line testing hours.
Extreme Climate Performance & Lifecycle Assurance Operations
Molded from premium, ultra-rugged PC polymer, this flagship terminal block operates perfectly under severe environmental stresses across a wide temperature spectrum of -40°C to +105°C. The heavy-duty clamping bolts maintain tight contact pressure and resist vibration-induced loosening, keeping contact resistance ultra-low (≤0.25 mΩ) over years of use. Permanent, high-contrast laser markings on the clear polycarbonate shield make circuit mapping and safety inspections fast, protecting critical dual-power systems from human error.
