The enclosure is manufactured from thick rotomolded HDPE material. The rigid plastic housing delivers excellent shock resistance to withstand repeated loading, transport and on-site knocks. Four heavy-duty swivel castors are fitted at the base for flexible movement, and lockable latches firmly fasten the front hinged door. The cabinet reaches IP54 ingress protection, preventing dust intrusion and resisting light water splashes.
Working Principle
Three-phase mains power enters the cabinet through the 125A main inlet and feeds the integrated main busbar system. Current is separated into isolated output branches controlled by independent circuit protection devices. Each connected electrical load receives regulated power from its dedicated circuit; if short-circuit or overload occurs, the corresponding circuit breaker trips automatically without cutting power to all other connected equipment.
Typical Application Scenarios
This mobile power distribution box is widely adopted for applications requiring flexible temporary power:
-
Rated Input: 125A, 400V 3P+N+PE
Standard: IEC 60309 industrial plug & socket standard
Input Inlet: 1 × 125A red 5-pin industrial inlet
Output Sockets Layout:27 pcs × 16A 230V blue single-phase sockets
3 pcs × 32A 400V red three-phase sockets
Each output circuit is equipped with independent miniature circuit breakers. Internal wiring adopts tinned copper busbars to lower electrical resistance and avoid oxidation under continuous heavy loads. Engineers can arrange loads evenly on three phases to maintain balanced three-phase operation.
Compliance & Safety Standards
The power distribution cabinet complies with IEC 60309, IEC 60439-1 low-voltage switchgear assembly standards. All conductive internal components are reliably earthed. Clear socket labelling and phase identification simplify safe connection and routine electrical inspection by site electricians.
1: What is the cabinet weight and outer dimension for shipping and container loading calculation?
We can provide exact outer dimensions and net/gross weight upon request to help you calculate sea freight costs and container space planning.
2: Are spare parts available separately (sockets, circuit breakers, castors, latches) for after-sales maintenance?
Yes. All wearing components including industrial sockets, MCBs, swivel casters and door locking latches can be supplied as separate spare parts for rental companies' long-term maintenance.
3: Is the internal busbar tinned copper? What is the cross-section size of main busbar?
Internal main busbars are made of tinned copper to resist oxidation. We can provide the exact busbar cross-section specification sheet on demand for your technical tender documents.
4: Can you print our company logo or rental brand marking on the cabinet door?
Custom branding options are available, including silk printing and adhesive label customization on cabinet surfaces, subject to minimum order quantities.
