Breaking capacity is 36 kA at 415V AC (Ics = 100% 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 200A (160-200A) – and an adjustable magnetic short-circuit setting from 6 to 10 times In. 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 DN2-250 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.
