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 Lauritz Knudsen AU Standard RCCB · 4P (FP) · 40 A · 100 mA · Type Adi genuine and warranty-backed?

Yes. Every Lauritz Knudsen 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 Lauritz Knudsen 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.
