Breaking standard 600V/200A market limits, our Through-Wall Power Terminals deliver up to 600A/1000V capacity and 125°C automotive-grade thermal tolerance. With UL94 V-0 materials and IP67 sealing, they provide a future-proof, robust connection for modern ESS, EV batteries, and heavy-duty applications. 600A/1000V High-Power Capacity Outperforming standard 200A terminals, this series supports up to 600A continuous current and 1000V. It provides essential power headroom for demanding high-voltage battery and rapid-charging architectures. 125°C Automotive Thermal Tolerance Exceeding the typical 105°C industrial limit, our PA66/PBT housing safely operates up to 125°C. This critical safety buffer prevents thermal degradation under continuous high-current loads. Panel-Integrated IP67 Sealing Select models feature robust IP67 waterproof and dustproof bulkhead seals. This secures panel cutouts against moisture ingress, ensuring safe high-voltage isolation for exposed outdoor equipment. Vibration-Resistant M4-M12 Mounting Offering M4 to M12 thread options for diverse cable lugs, the secure bolted fastening guarantees ultra-low contact resistance and highly vibration-proof connections in mobile environments. APPLICATIONS Engineered for seamless high-voltage integration, our Through-Wall Power Terminals are widely utilized in commercial Energy Storage Systems (ESS), Electric Vehicle (EV) battery enclosures, and heavy-duty Power Distribution Units (PDUs). By providing a secure, weather-resistant, and low-loss bulkhead connection, they are the ideal choice for engineers developing reliable power routing architectures in RVs, marine applications, and off-grid power stations.
