Both the JXF-1000 and JXF-2000 are indoor/outdoor Jiye distribution and junction enclosures sharing the same electrolytic steel + epoxy coating platform, but they differ in electrical rating, protection level, and construction details: (1) Voltage — JXF-1000 is rated 400V only; JXF-2000 supports 400V or 690V selectable, suitable for industrial 690V systems. (2) Current — JXF-1000 up to 400A; JXF-2000 offers discrete ratings of 63A/100A/160A/250A (smaller, more junction-oriented). (3) Protection — JXF-1000 IP44/IP54 outdoor; JXF-2000 reaches IP54/IP65 outdoor (higher, dust-tight) and IP43 indoor. (4) Cable entry — JXF-1000 bottom entry only; JXF-2000 has pre-punched top AND bottom knock-outs for overhead or underground routing. (5) Mounting — JXF-2000 adds a detachable galvanized internal mounting plate for bench assembly. (6) Factory sealing — JXF-2000 seals all openings with protective plugs at the factory. Choose JXF-2000 for higher IP, 690V, top/bottom entry, and junction/terminal applications; choose JXF-1000 for higher current (up to 400A) distribution at 400V.

The detachable galvanized internal mounting plate is a key time-saver and quality enhancer: (1) Bench assembly — the plate can be removed from the enclosure and clamped to a workbench, where components (DIN-rail MCBs, contactors, terminal blocks, PLCs) can be mounted and pre-wired in a flat, well-lit, ergonomic position rather than reaching inside a confined box. (2) Better wiring quality — working on a flat surface produces neater, more consistent wiring and easier torque verification on terminals, reducing the risk of loose connections. (3) Galvanized corrosion resistance — the plate is galvanized steel, so it resists corrosion even in humid environments and provides a reliable earth/PE bonding surface. (4) Easy re-installation — the pre-wired plate is simply bolted back into the enclosure, and field cables are terminated to the pre-routed terminals. This approach cuts on-site installation time significantly and is especially valuable for repeat or high-volume panel builds.

All top and bottom cable entry knock-outs are sealed at the factory with protective plugs or sealing plates to: (1) Maintain enclosure integrity during transport, handling, and storage — preventing dust, moisture, insects, and debris from entering before installation. (2) Preserve the IP rating — an unsealed knock-out is an open hole that would completely defeat the IP54/IP65 protection. (3) Allow selective opening — only the knock-outs actually needed for cable entry are opened on-site; the rest remain sealed. On-site procedure: (a) Identify the knock-out locations matching your cable routing (top entry for overhead, bottom entry for underground). (b) Remove the protective plug or punch out the knock-out. (c) Fit an IP-rated cable gland of the correct size and tighten to the specified torque. (d) Verify the seal. Leaving unused knock-outs sealed is essential to maintain the enclosure's protection rating. Never leave an opened knock-out without a gland or blanking plug.

Yes. The JXF-2000 is available with a selectable 690V AC rated voltage (Ui up to 690V, Uimp up to 8kV depending on configuration), making it suitable for 690V industrial distribution systems commonly found in: heavy industry, mining, oil & gas, renewable energy plants (wind/solar), and large motor drive installations. When specifying for 690V: (1) Confirm the 690V configuration at ordering so the correct insulation coordination and clearance/creepage distances are applied internally. (2) Ensure all internal components (MCBs, contactors, terminal blocks, busbars) are themselves rated for 690V. (3) For 690V systems with higher fault levels, confirm the short-circuit withstand rating of the internal busbar system matches your prospective fault current. (4) Apply appropriate 690V labeling and warning signage. Do not use a 400V-configured enclosure in a 690V system, as the internal clearances may be insufficient.

IP65 protection means: First digit '6' (dust-tight) — no ingress of dust; complete protection against contact. Second digit '5' (water jets) — protection against water jets (12.5mm nozzle, 12.5 L/min, 30kPa) projected from any direction; limited ingress permitted (no harmful effect). For outdoor installation this means the JXF-2000 IP65 variant can withstand: direct rain, wind-driven rain, water spray from hoses during cleaning, and dusty environments. What IP65 does NOT cover: (1) Temporary or continuous submersion (that requires IP67/IP68). (2) High-pressure water jets (>30kPa, e.g., pressure washers — that requires IP66). (3) Condensation inside due to temperature cycling — ensure adequate internal climate control (heaters, vent plugs) for large temperature swings. (4) UV and corrosion of the exterior coating — the epoxy coating handles normal UV, but extreme coastal or chemical atmospheres may require a higher-grade finish. Always install a canopy for prolonged direct sun/rain exposure and ensure cable glands are IP65-rated.

The door choice depends on whether you need visual access to internal devices: (1) Solid metal door — recommended for general distribution, junction, and control applications where no visual indication is required. It offers the highest mechanical strength and impact resistance, a clean uniform appearance, and the simplest sealing. Choose this for outdoor electrical distribution panels, terminal boxes, and any application where the door is opened only for maintenance. (2) Transparent perspective door (outdoor only) — recommended when you need to read meters, check pilot lights, or inspect component status without opening the enclosure (e.g., metering panels, status-indication control panels, remote/unmanned sites). The window is impact-resistant polycarbonate or tempered glass. Note that the window area has slightly lower impact resistance than solid metal and may need cleaning to maintain visibility. The transparent door still uses the same V-shaped drip-edge seal to maintain IP54/IP65. For indoor models, only the solid metal door is offered since weather sealing is not a concern.
