Read: Havells vs ABB vs Lauritz Knudsen: Which Switchgear for Your Home? →
Which is the best MCB brand in India: Havells, ABB or Lauritz Knudsen?
At correct specification, all three protect reliably; they differ in range, price and availability rather than trip-when-needed quality. Havells wins on availability and range breadth, ABB on engineering pedigree, Lauritz Knudsen on premium build at keen prices.
Is Lauritz Knudsen the same as L&T Switchgear?
Yes; it is the renamed erstwhile L&T Switchgear business, continuing the same Indian manufacturing legacy under new ownership and branding. Ranges like Tripper and EXORA carry that lineage forward.
Can I mix MCB brands in one distribution board?
Electrically yes; DIN-rail standards make devices interchangeable, and a mixed board protects correctly if each device is rightly rated. Single-brand boards are still preferable for spares, warranty simplicity and appearance.
Is ABB VM4 Mechanical Interlock Unit genuine and warranty-backed?

Yes. Every ABB product on Elume is 100% genuine, sourced through authorised channels, and carries the manufacturer's standard warranty.

Do you deliver across India?

Yes - we deliver pan-India, usually within 3–7 working days. Delivery is free on orders of ₹4,000 and above; a flat ₹100 fee applies from ₹2,000 to ₹4,000 and ₹200 below ₹2,000.

Can I get a GST invoice?

Yes. Enter your GSTIN at checkout and we issue a GST invoice with tax shown separately, so businesses can claim input tax credit.

Is there a wholesale or bulk rate?

Yes. Orders of 15 or more pcs get a wholesale rate about 5% below the listed Elume price - shown on every product page.

What if I find it cheaper somewhere else?

Tell us. If the same ABB product is listed for less, GST and delivery included, by an authorised Indian online seller, we match that price - before you order or within 7 days of ordering. The terms are on our lowest-price guarantee page.

What is the return policy?

Unused items in original packaging can be returned within 7 days of delivery, with free return shipping.
