What buyers get: spec-tight builds, standards-compliant testing, and tidy documentation—so your harnesses, panels, motors, and cables pass audits and install without surprises.

What we source & build

Wire harnesses

• Automotive/industrial looms, battery/EV sub-harnesses, control-panel looms, over-moulded connectors, label/marker sets.
  
• Process: cut/strip/crimp with in-line monitoring, ultrasonic welding, 100% continuity & hipot.
  

LV switchgear & assemblies

• Devices: MCB/MCCB, MPCB, contactors, overload relays, pushbuttons, isolators.
  
• Panels/boards: power & control, form-rated assemblies with busbar systems, thermal design and short-circuit design verification.
  

Motors

• IE-class 3-phase induction motors (IE2/IE3/IE4) with BIS-aligned nameplates; custom shafts/flanges; inverter-duty varnish systems where specified.
  

Cables

• House/control wiring (FR/FR-LS/LSZH), instrumentation & control, VFD cables, armoured XLPE LV/MV power cables; CPR (EU) classes on request.
  

The standards we build to (and show in your file)

• Harnesses: IPC/WHMA-A-620 acceptance (workmanship classes 1/2/3), crimp pull-tests, strain-relief, soldering, marking.
  
• Switchgear devices: IS/IEC 60947 series (general rules; switches; contactors/overload relays).
  
• Assemblies/panels: IS/IEC 61439 (design/type verification—temperature rise, dielectric, short-circuit strength; routine tests).
  
• Motors: IS 12615 (IE efficiency classes), routine tests (insulation, HV, vibration, load/no-load).
  
• Cables (India): IS 694 (PVC 450/750 V) • IS 7098 (XLPE power).
  
• Fire/smoke/halogen (export options): IEC 60332-1-2 (flame), IEC 60754-1 (halogen acid gas), IEC 61034 (smoke density).
  
• EU CPR (where needed): EN 50575 DoP & classification for reaction to fire.
  

Quality & test plan (typical)

Harnesses

• 100% continuity/hipot; crimp pull to spec; connector retention; loom board sign-off; first-article with cut-list & pinout maps.
  

Switchgear & panels

• Device routine tests per 60947; panel design/type verification file (temperature-rise, dielectric, short-circuit) + routine tests on every board; torque charts & wiring ferrule schedule.
  

Motors

• Winding resistance, surge/insulation, no-load & load efficiency vs IE class, vibration & noise; paint film build & corrosion checks when outdoor rated.
  

Cables

• Conductor DC resistance, insulation thickness/spark test, HV test; LSZH options validated to IEC flame/halogen/smoke; CPR DoP where specified.
  

How IndiaUnbox de-risks your program

1. Spec to drawing — harness schematics & BOMs; GA/single-line/SLD for panels; motor data sheets; cable spec matrix (fire class, CPR where needed).
   
2. Right factories, right certs — IPC-trained harness lines, type-tested panel shops, BIS-licensed motor plants, NABL-backed cable labs.
   
3. Samples → FAI/PPAP — build boards, labelled looms, device datasheets; 61439 design/type-verification pack; IE-class motor test cards; cable COPQ & fire-test plan.
   
4. Compliance pack (per lot) — IPC acceptance records; 60947 routine test sheets; 61439 design/type-verification summary + routine tests; IS 12615 nameplate & BIS license details; IS 694/7098 CoCs; optional CPR DoP.
   
5. Cost & continuity — VA/VE on conductor sizes, connector families, panel busbar sizing, cable constructions; dual-source options; phased capacity plans.
   
6. Logistics — serialized harness labels, panel nameplates & rating decals, cable drum handling (lagging & moisture control), ISPM-15 for any wood.
   

Typical MOQs & lead times (guide)

• Harnesses: 100–1,000 sets/SKU • 4–8 weeks post approval
  
• Switchgear panels: 10–100 boards/SKU • 6–10 weeks (incl. design/type docs)
  
• Motors: 50–500 units/SKU • 5–8 weeks
  
• Cables: 2–20 km/SKU (construction-dependent) • 4–7 weeks
  

What you’ll receive in your documentation bundle

• Drawings (Rev-controlled), BOMs, wiring diagrams/SLD, terminal schedules
  
• Test records (IPC pull-tests/continuity; 60947/61439 sheets; IE-class checks; cable HV/flame/LSZH as ordered)
  
• Certificates/Declarations: BIS license refs (motors), CoCs (IS 694/7098), CPR DoP (if EU), material CoAs, nameplate artwork proofs
  

Bottom line: We turn India’s electricals ecosystem into audit-ready harnesses, panels, motors and cables—built to the right IPC/IS/IEC/CPR frameworks, documented cleanly, and delivered on a schedule and cost structure you can defend.
