Discover our flagship residential and light industrial electrical cabinets, meticulously configured for optimum thermal performance, circuit protection, and code compliance.
Established in 2011 in the industrial heart of Zhejiang Province, China, Hangzhou SN Electrical Co., Ltd. has grown to become a globally trusted, professional manufacturer of low-voltage electrical distribution systems, smart electrical infrastructure, and high-precision power management equipment.
By integrating design, sheet metal fabrication, component assembly, and rigorous ISO-certified quality control within a single 18,000 square meter facility, we guarantee the safety and reliability that modern infrastructure projects require. With more than 250 skilled employees, we offer comprehensive OEM and ODM solutions to clients in Europe, North America, South America, Southeast Asia, the Middle East, and Africa.
The acceleration of urban electrification, smart homes, and renewable residential power configurations demands highly stable low-voltage distribution platforms. We configure modern products tailored for global residential growth.
High-density vertical structures require smart space usage, reliable overheating mitigation, and rigorous electrical division. Our multi-tier branch boxes ensure robust continuous power flow.
Integration of residential solar panels, domestic battery systems, and EV chargers demands dynamic, dual-busbar boxes that manage diverse AC and DC currents safely.
Our advanced sheet metal custom structures allow the seamless physical integration of smart electrical meters, network gateways, and multimedia distributions.
Electrical standards vary widely across global markets. As a certified manufacturer, we verify that our products meet the exact technical requirements of the importing region. Every residential distribution box we engineer undergoes strict quality testing prior to dispatch.
We configure localized distribution configurations to guarantee smooth on-site inspections:
From standard light control loops to multi-apartment distribution networks, our products are engineered to excel in diverse installations.
In modern multi-family apartment towers, power distribution needs to be compartmentalized, secure, and compact. Our 160A apartments distribution cabinets include dedicated overload and short-circuit protection for every unit. Lockable glass and steel double-doors guarantee that only certified service technicians can access primary terminals.
As global smart homes integrate energy storage systems (ESS) and smart lighting setups, standard load centers fall short. Our customized power distribution switchgears accommodate hybrid breakers, automated relays, and communication terminals, facilitating a centralized structure for clean modern home designs.
Outdoor electrical junctions and sub-panels require advanced sealing to resist moisture, dust, and insects. Using premium polyurethane foam-in-place gaskets (FIPG) and outdoor-grade polyester powder paints, our wall-mounted cable branch and distribution cabinets ensure long-term IP65 reliability in coastal areas or high-humidity regions.
Upgrading older electrical networks presents space constraints. Our compact Pz30 distribution series and customized flush-mount panels provide ultra-shallow depth configurations, making it simple for electrical contractors to install high-density modern circuit protection inside existing, narrow walls.
