Question 1

What is a 3-in-1 busbar machine?

Accepted Answer

A 3-in-1 busbar machine performs the three core busbar operations — cutting (shearing), bending and punching — in a single machine, so a panel builder can process copper or aluminium busbar without moving it between separate tools. Namsung NSB machines add PLC digital-angle bending and waste-free shearing. Portable models such as the NSB 505/506 also compress terminals, making them 4-in-1.

Question 2

What busbar sizes can these machines process?

Accepted Answer

Namsung NSB machines handle busbar from about 120 mm wide (portable NSB 505/506) up to 220 mm wide on the NSB 607A, with hole punching from Ø3.4 mm to Ø25 mm. EHRT CNC machines process busbar 15–200 mm wide and 3–16 mm thick.

Question 3

What is the difference between the Namsung NSB and EHRT busbar machines?

Accepted Answer

Namsung NSB (Korea) machines are compact and portable 3-in-1 / 4-in-1 units that cut, bend and punch on one frame — ideal for small to mid-size switchgear shops and on-site work. EHRT (Germany) machines are fully CNC punching and bending machines built for high-volume, high-precision automated production lines, with ±0.1° bending accuracy and Beckhoff CNC control.

Question 4

How much does a busbar processing machine cost in India?

Accepted Answer

Price depends on the machine class: portable Namsung 3-in-1 units are the entry point, while automated EHRT CNC punching and bending lines are a larger capital investment. ElectroTechnix supplies the full range — contact the Bangalore team on +91 78920 28330 or WhatsApp for current pricing and specifications for your busbar size.

Question 5

Are these genuine imported machines?

Accepted Answer

Yes. ElectroTechnix supplies genuine EHRT machines from Germany and Namsung machines from South Korea. EHRT has built busbar processing machines for over 50 years; Namsung has manufactured and exported busbar machines since 1976.
