Breaking capacity is 36 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 160A (128-160A) – with a fixed magnetic short-circuit trip at 9 times the rated current (1440A here). That adjustability lets you trim the overload trip 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 (120 mm mm2 lugs), add the matching DU250 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, 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.
