Looking for the L&T DY250U1 MCCB 160-200A 3 Pole? This is the genuine Lauritz Knudsen (formerly L&T Switchgear) DY series 250A frame moulded case circuit breaker, catalog number CM98195OONO, made for feeder and sub-distribution protection in commercial buildings, small 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.

The DY250U1 covers the 125A to 250A band with an adjustable overload (thermal) setting of 0.8 to 1.0 x In – this unit is supplied in the 160-200A range, so you set the exact trip current on the dial within that window. Short-circuit protection is a fixed magnetic trip at 9 x In. Spreader terminals and phase barriers are included in the box, so terminating up to 120 mm² cable is straightforward with no separate accessory order.

With a 10 kA breaking capacity at 415V AC (Ics = 100% of Icu), the DY250U1 suits installations where the prospective fault level does not exceed 10 kA – typically sub-distribution feeders downstream of a larger incomer. For higher fault levels in the same frame, look at the DU250C (25 kA), DU250 (36 kA) or DU400N (50 kA) – we stock those too.

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 and IEC 60947-2. Current rating is displayed on the mid-cover and the lockable shroud on the thermal knob prevents unauthorised changes to the overload setting.

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.
