Looking for the L&T DU250C MCCB 200A 3 Pole? This is the genuine Lauritz Knudsen (formerly L&T Switchgear) DU series moulded case circuit breaker, catalog number CM90631OONO, 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 25 kA at 415V AC, with Ics = 50% of Icu. The DU range gives you an adjustable thermal (overload) setting from 0.8 to 1.0 times In – this unit covers 200A (160-200A) – with a fixed magnetic short-circuit trip at 9 times the rated current (1800A here). That adjustability lets you trim the overload trip to the actual load and cable size during commissioning.
This catalog number comes with spreader terminals included in the box, so terminating aluminium or copper cables up to 120 mm² is straightforward and you do not have to order spreaders separately. Phase barriers are also supplied with every 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, IEC 60947-2 and EN 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 25 kA MCCB like the DU250C?
Use it where the prospective short-circuit level at the installation point is 25 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. If you need a higher fault level, the DU range goes up to 50 kA (DU400N) and the dsine DN range covers 25-100 kA – we stock both.
Can I adjust the trip settings on this MCCB?
Yes, partly – the DU250C has an adjustable thermal (overload) dial from 0.8 to 1.0 times In, so this 200A unit can be set anywhere in the 200A (160-200A) range. The magnetic short-circuit trip is fixed at 9 times the rated current (1800A on this unit). If you need finer electronic settings, look at the DN range with MTX microprocessor releases.
Are spreader terminals included with this MCCB?
Yes. This catalog number CM90631OONO is the with-spreader-terminals variant – spreaders and phase barriers come in the box, which makes terminating up to 120 mm2 cable easy.
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?
Every order comes with a GST invoice suitable for ITC claims and project billing. Payment is prepaid through PhonePe – UPI, cards and netbanking are all accepted. For bulk quantities and project rates, WhatsApp us on +91 78160 62494.
