DFW-12 is a simple cable branching device that splits one incoming cable into multiple outgoing cables. It typically does not contain switching or protection devices (unless specified). A ring main unit (RMU), like our HXGN15-12, includes load break switches and/or circuit breakers for switching and protection. Choose DFW-12 when you only need cable distribution at a lower cost, and RMU when you need switching and protection capabilities.

Yes, absolutely. DFW-12 is designed for outdoor installation with IP67 protection rating, meaning it is fully dust-tight and can withstand temporary water immersion. The 304 stainless steel enclosure provides excellent corrosion resistance. It is suitable for installation in rainy, coastal, and industrial environments with high humidity or corrosive atmospheres.

Standard configurations include 2-way, 3-way, and 4-way branch boxes. GOHO can also customize 5-way, 6-way, or 8-way configurations depending on your specific requirements. Each branch can handle up to 630A rated current. Contact our engineering team with your single-line diagram for a customized solution.

DFW-12 with European-style plug-in connectors supports cable cross-sections from 25mm² to 400mm² (and up to 630mm² for larger models). For cable lug connections, we can accommodate various cable sizes depending on the connector type. Please specify your cable size when ordering so we can match the appropriate connectors.

Surge arresters (lightning protection) are available as an optional add-on for DFW-12 cable branch boxes. We recommend including surge arresters for installations in lightning-prone areas or for critical load applications. Other optional accessories include fault indicators, temperature sensors, and monitoring devices for smart grid integration.
