8 Sockets 3 Phase Distro Rack Box

This 8-socket distro provides a compact aluminum housing designed for industrial and stage equipment. With 220V input and 110V output, it offers a straightforward power path for mixed voltage setups. The L21-30 twist-lock compatible input supports secure connections in dynamic environments, while the 8-output arrangement helps simplify large equipment racks. Its rugged construction suits both indoor venues and temporary outdoor installations where durability matters. Always verify your load distribution to avoid overloading any single circuit.
JUNMAN 6 Channel L21-30 Distro

The JUNMAN unit consolidates six channels with a 3‑phase input and 12 Edison outlets. This configuration is well-suited for events where multiple devices require reliable 120V outputs from a single L21-30 feed. The black enclosure provides a discreet, professional appearance on stages or in rehearsal spaces. When wiring, confirm clearance and phase balancing across outlets to minimize neutral and ground stress and ensure balanced loads across phases.
Stage Audio Lighting Power Distribution Box
This 380V waterproof distro is designed for outdoor and rugged use, supporting 63A 5-pin 3‑phase input/output. The IP44 rating suggests reliability in damp or dusty environments, making it suitable for outdoor stages or festival setups. The design supports synchronizing multiple rack units and offers multiple CEE 3‑pin outputs. Operators should verify connector compatibility with existing gear and use weatherproofing practices to maintain safety during rain or high humidity.
3 Phase Power Distribution Box (CEE)

This three-phase distribution box emphasizes a CEE format with a 5P 32A input and 380V operation. Marketed toward stage and AV control, it consolidates power for lighting, video, and audio controls in one enclosure. Users should ensure proper cable management to prevent heat buildup and confirm that all outlets and breakers comply with local electrical codes. Its robustness makes it a good candidate for touring productions requiring quick power redistribution between setups.
Three Phase Splitter DIN Rail Box

ANGGREK’s DIN rail splitter is designed for space-saving installations with a four-pole output capable of handling 250-450V. The DIN rail approach makes it a good fit for control panels or rack-mounted cabinets where modularity and quick wiring adjustments are required. The device’s compact footprint helps maximize available rack space, though it may require additional protection or enclosure if used in harsh environments. Consider its capacity against your total expected load per rail to avoid overloading any single circuit.
2-Level Junction Box with DIN Rail

Walfront offers a two-level junction box with DIN rail mounting and a transparent dust cover for quick inspection of wiring. This unit emphasizes safe, organized power distribution with an isolation barrier between terminal blocks to curb short circuits. Its design supports easy installation on guide rails or base plates, and the transparent cover aids ongoing monitoring, reducing the need to open enclosures during inspections. This option is useful as a supplementary distribution node within a larger system or for test benches requiring rapid access to connections.
Buying Guide: Key Considerations for 3 Phase Distro Boxes
- Voltage and phase compatibility: Verify whether the unit supports your regional supply (e.g., 220–240V single-phase vs. 380–415V three-phase) and whether it can provide both 3-phase and single-phase outputs as needed.
- Input/output configurations: Consider the number of sockets, their types (Edison, CEE, NEMA), and the layout that best fits your racks or stage setup. Balance between distribution density and ease of access.
- Durability and enclosure rating: For outdoor or touring use, prefer weatherproof, IP-rated enclosures with rugged housings (aluminum, reinforced plastics) and protective gaskets.
- Safety features: Look for isolation barriers, correct labeling, thermal protection, and clear separation of high and low voltage areas to minimize short circuits and overheating risks.
- Mounting and footprint: DIN rail compatibility and rack-mount readiness help integrate the distro into control panels or equipment racks. Ensure there is sufficient clearance for cables and connectors.
- Ease of installation: Quick-connect inputs, clearly accessible outlets, and logical wiring paths save setup time during load-in and changeovers.
- Scalability: If future expansion is likely, select units with modular or stackable designs, enabling additional channels or cascading boxes without reworking existing layouts.
- Maintenance and monitoring: Transparent covers, labeling, and accessible terminals simplify ongoing maintenance and fault tracing.
