Looking for the L&T DN0-100D MCCB 40A 4 Pole? This is the genuine Lauritz Knudsen (formerly L&T Switchgear) dsine DN series moulded case circuit breaker, catalog number CM97919OOF2OG, made for feeder, incomer and sub-distribution protection in commercial buildings, industries and OEM panels. We stock it at our Chamrajpet shop in Bengaluru with a GST invoice on every order, same-day dispatch for orders placed before 4 PM (Monday to Saturday), and delivery across all of Bengaluru including outskirts. Free store pickup is available. For project and bulk rates, WhatsApp us on +91 78160 62494.

Breaking capacity is 36 kA at 415V AC (Ics = 50% of Icu). The dsine DN range gives you a thermal-magnetic release with an adjustable thermal (overload) setting from 0.8 to 1.0 times In – this unit covers 40A (32-40A) – and a fixed magnetic short-circuit trip at 9 times In (375 A factory setting on ratings up to 50A). That adjustability lets you trim the protection to the actual load and cable size during commissioning.

Spreader terminals are not included with this catalog number – if your panel needs them for cable termination, add the matching DN0-100 4 pole spreader link set and, for panel-door operation, the direct or extended rotary handle from the Frequently Bought Together section below. One set covers one MCCB. Phase barriers are supplied with the unit.

Practical panel-builder details: no load-line bias, so supply and load can connect to either side; clear ON / TRIP / OFF indication; suitable for isolation; conforms to IS/IEC 60947-2.

Note on branding: L&T Switchgear is now Lauritz Knudsen Electrical & Automation (renamed in May 2024). Depending on stock, the unit may carry either the L&T or Lauritz Knudsen name. The catalog number, specifications and quality are identical.

❓ Frequently Asked Questions

Where can I use a 36 kA MCCB like the DN0-100D?

Use it where the prospective short-circuit level at the installation point is 36 kA or less – typically incomers and feeders in commercial and industrial distribution boards. Your panel designer or electrician works this out from the upstream transformer rating. The dsine DN range covers 25 kA, 36 kA and 50 kA variants – if you need a different fault level, ask us on WhatsApp and we will point you to the right catalog number.

Can I adjust the trip settings on this MCCB?

Partly – the DN0-100D has an adjustable thermal (overload) dial from 0.8 to 1.0 times In, so this 40A unit can be set anywhere in the 40A (32-40A) range. The magnetic short-circuit trip is fixed (375 A factory setting on ratings up to 50A). If you need fully adjustable electronic settings, look at the DN range with MTX microprocessor releases.

Are spreader terminals included with this MCCB?

No – CM97919OOF2OG is the without-spreader variant, which keeps the price lower. If your panel needs spreader terminals for 4 pole cable termination, add the matching DN0-100 4 pole spreader link set from the Frequently Bought Together section below – one set covers one MCCB.

How fast can you deliver in Bengaluru?

Orders placed before 4 PM, Monday to Saturday, are dispatched the same day. We deliver across all of Bengaluru including outskirts like Sarjapur, Anekal and the airport side. Delivery charges are confirmed with you before dispatch. You can also pick up free from our Chamrajpet shop.

Do I get a GST invoice and what are the payment options?
