IP65 assemblies, distinct from enclosure testing

Completed AJB, ACDB and DCDB products are offered as IP65 solar electrical boxes.

Applicable SIBOX enclosure models have IP66 test reports. A completed electrical assembly does not automatically retain the empty enclosure's IP66 rating. No independent certification of complete assemblies is claimed here.

Components & assembly

Customization

Review. Confirm. Assemble.

Inputs, outputs, string count, protection devices, electrical configuration, cable entries, internal wiring, terminal layout and enclosure dimensions are coordinated to the approved requirement.

Electrical specifications, component selection and relevant drawings are reviewed with the customer before assembly and wiring.

Documented assembly checks

Continuity and wiring verification.

Completed AJB, DCDB and ACDB boxes undergo continuity testing and wiring verification before packing and dispatch.

Supply starts from one unit. Final device ratings, component availability and protection arrangements are confirmed for the order.

What to share

Start with your system requirements.

  • AJB, ACDB or DCDB requirement
  • System voltage and relevant electrical ratings
  • Number of inputs and outputs
  • Required protection components and preferred enclosure
  • Single-line diagram or technical drawing, if available
  • Quantity and delivery destination

Discuss the right configuration.

Share the available technical details for review. The final assembly follows confirmed specifications and component selection.
