Question 1

What are bus bar supports and why are they important?

Accepted Answer

Bus bar supports are insulated mounting brackets that hold copper or aluminum bus bars in position within electrical panels. They provide mechanical support, electrical insulation, and proper spacing between phases. Quality supports prevent bus bar sagging, maintain clearances, and ensure safe operation even during fault conditions.

Question 2

Can brass components handle high short-circuit currents?

Accepted Answer

Yes, brass has excellent arc resistance and can withstand short-circuit conditions better than many alternatives. However, the entire switchgear assembly must be rated for expected fault currents. Our components are designed for typical LV switchgear fault ratings up to 50kA when properly assembled per standards.

Question 3

What plating should I choose for my application?

Accepted Answer

Tin plating is standard for indoor panels and provides good corrosion protection. Nickel plating is recommended for harsh industrial environments or outdoor installations. Silver plating offers lowest resistance for high-current applications (500A+) but costs more. Bare brass is economical but oxidizes over time.

Question 4

Are your parts compatible with standard DIN rail systems?

Accepted Answer

Yes, we manufacture components for standard 35mm DIN rail (EN 60715) as well as other mounting systems. Our terminal blocks, cable glands, and accessories are designed for easy installation on DIN rail. Custom mounting options available for OEM switchgear designs.

Question 5

How do I select the correct current rating?

Accepted Answer

Component current rating depends on several factors: conductor size, ambient temperature, enclosure ventilation, and duty cycle. As a general rule, derate components by 20% for enclosed panels. For critical applications, consult IS 13947 or IEC 61439 standards. We provide technical support for proper sizing.

Question 6

Do you manufacture custom switchgear components?

Accepted Answer

Yes, we specialize in custom brass parts for OEM switchgear manufacturers. We can work from drawings, samples, or design requirements. Common custom items include unique bus bar supports, specialized terminal blocks, and branded components. MOQ typically 1000-5000 units depending on complexity.

Question 7

What testing is required for switchgear assemblies?

Accepted Answer

Complete switchgear assemblies must undergo type testing and routine testing per IS 13947 or IEC 61439. This includes temperature rise tests, short-circuit tests, dielectric tests, and mechanical tests. While we test individual components, final assembly testing is the responsibility of the panel builder.

Question 8

Can I get matching hardware and fasteners?

Accepted Answer

Yes, we supply complementary brass hardware including nuts, bolts, washers, and mounting screws in matching finishes. This ensures uniform appearance and eliminates compatibility issues. We can package complete hardware kits for your panel assembly needs.
