Mechanism / AccessoriesMechanism
Ratings as published by Legrand (shop.legrand.co.in). Verify critical parameters against the datasheet before specifying.
The letter after the sensitivity says which earth-fault currents the breaker can sense. Every type trips on a plain AC leak; the higher types also catch the leaks electronics produce. Same rating, different type, different price.
Type AC
Senses sinusoidal AC leakage only. Enough for lighting, geysers, heaters and plain socket circuits.
Type A
THIS UNIT
Senses AC and pulsating DC leakage, the kind inverter air conditioners, washing machines, UPS units, solar inverters and EV chargers produce. A Type AC unit can stay blind to those faults. Covers everything Type AC does. The safe default for a modern home.
Type A APR
Type A with high immunity to nuisance tripping: a short delay rides through lightning surges and switching transients. For circuits where a false trip costs more than the delay: servers, refrigeration, long cable runs.
Sensitivity is a separate choice: 30 mA protects people from shock; 100 mA and 300 mA units are for fire protection or as an upstream main. Type definitions per IEC/EN 61008 and 61009.
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 Legrand DX3 RCBO · 4P (FP) · 20 A · 300 mA · Type A · 6 kA genuine and warranty-backed?

Yes. Every Legrand 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 Legrand 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.
