Four engineering-grade product lines—distribution boards, junction boxes, isolators, and industrial plugs. Fully certified, tested in-house, and optimized for global distribution and demanding project tender requirements.
Zhejiang Selhot Electric Co., Ltd is a professional manufacturer of waterproof electrical enclosures and commercial electrical equipment. Our product range spans IP66 distribution boxes, weatherproof junction boxes, IEC 60947-3 rotary isolator switches and IEC 60309 industrial plugs and sockets. As a CE, RoHS, TÜV and ISO 9001 certified factory with 20+ years of R&D experience, we deliver one-stop OEM/ODM services — custom hole drilling, laser marking and mold development — to distributors and project buyers worldwide.




One-stop OEM/ODM for all SELHOT product lines — distribution boxes, junction boxes, isolation switches and IEC 60309 industrial plugs. From color matching and precision hole drilling to private mold development.
RAL color matching for distribution board shells, junction box housings, isolator enclosures and industrial plug bodies — in ABS or PC. Standard grey and white, or custom greens, blues and municipal colors for outdoor, solar and infrastructure projects across all four product lines.
Modular distribution boards from 4-way to 36-way; junction boxes from 100×100 mm to 800×600 mm; rotary isolators in 2P–5P from 10A to 125A; IEC 60309 plugs and sockets from 16A to 125A. Custom wall thickness and internal capacity engineered per category.
UV-stabilized PC or flame-retardant ABS (UL94 V-0/V-2) for distribution and junction enclosures. Thermoplastic isolator housings with padlockable covers. Industrial plug bodies in high-impact polymer with color-coded voltage rings per IEC 60309.
Custom knockout positions and cable gland entries (M20/M25/M32/M40) for distribution boards and junction boxes. Removable knockout designs for on-site flexibility, or factory pre-drilling to your conduit schedule. Isolator and plug categories support tailored cable entry layouts on request.
Wall-mount distribution boards with 35 mm DIN rails and busbars; surface or wall-mount junction enclosures with hinged lids; surface-mount rotary isolators with padlockable OFF; panel-mount or portable IEC 60309 sockets for construction and factory power distribution.
Logo laser marking, silk-screen printing and custom data plates on distribution boxes, junction enclosures, isolator covers and plug housings. Private mold co-development (SHPZ / SHK / custom plug tooling) from concept sketch through validation — for distributors building exclusive product lines in any category.
IP65/IP66 distribution and junction enclosures with IK08/IK09 impact ratings per IEC 60529. IP65 enclosed rotary isolators for EV, PV and industrial disconnect. IP44 splash-proof and IP67 submersible IEC 60309 plugs and sockets — select the right ingress rating per product category and site environment.
From engineering support to certified production — the backbone behind every order.
Our expert team brings 20+ years R&D experience in enclosure design and manufacturing — supporting IP rating selection, IEC 60529 / EN 60670-1 compliance and project specs from RFQ to delivery.
Samples ship in 3–5 days and standard bulk orders dispatch within 15 days from our 20,000㎡ factory with 37 injection-molding lines.
Every batch undergoes IPX5/IPX6 waterproof, temperature cycling and IK08/IK09 impact testing. Products hold CE, RoHS and TÜV certification.
Production is monitored at every stage under ISO 9001, across a 20,000㎡ plant with 37 molding machines, 22 test stations and 800㎡ of laboratory space.
Engineered for solar & PV, EV charging, industrial manufacturing, construction, outdoor/marine and residential smart-home installations.
