Power Distribution Box

Power Distribution Box

A power distribution box serves as a critical hub for supplying electrical power to heavy-duty equipment such as industrial motors, pumps, and ventilation systems. Engineered to handle three-phase 380V power with substantial current capacities, it integrates advanced protective mechanisms including thermal overload relays, magnetic circuit breakers, and short-circuit safeguards to mitigate electrical hazards.

FAQs

 

Is the box pre-wired and tested?
Yes-all units are fully assembled, labeled, and undergo insulation resistance and continuity testing before shipment.

 

Can it control motor loads?
Yes. We offer versions with MCCBs and optional thermal overload relays or contactors for direct motor control.

 

Do you supply breakers from international brands?
Yes-ABB, Schneider, Siemens, or Eaton breakers can be installed upon request (price adjusted accordingly).

 

What's the difference between IP54 and IP65?
IP54 protects against dust ingress and water splashes (ideal for indoor plant rooms). IP65 is dust-tight and jet-water resistant-for outdoor or washdown areas.

 

How do you ensure quality?
Every unit is built per IEC 61439, tested for electrical safety, and inspected before packing. Test reports provided.
