Product details

Rated insulation voltage is 440 V, and the short-circuit breaking capacity is 6 kA (Icn), with an ultimate breaking capacity Icu of 20 kA.

DIN-rail mount, 2-pole width of 35 mm, depth 69 mm, height 88 mm. The IP20 enclosure (front) and IP40 (terminal side) suit installation in a dead-front panel.

C-curve (tripping characteristic C) means the magnetic trip operates at 5 to 10 times In (10 A to 20 A for this 2 A unit). That's the standard choice for moderate inrush loads — small motors, contactor coils, control transformers — where a B-curve would trip on energization but a D-curve would be too slow for cable protection. Overvoltage category III (OVC III) — the breaker is rated for fixed-installation distribution boards where transient overvoltages are higher than at the load side. The 440 V rated insulation voltage (Ui) covers common 400/415 V three-phase networks with margin.

Frequently asked questions

Will 2CDS251103R0024 drop into a panel that was specified around S202M-C16 without rewiring?

Not directly — the S202M-C16 is a 16 A, 2-pole, C-curve MCB on the same DIN-rail footprint, but the 2 A rating of the 2CDS251103R0024 is a different current level. Physical interchange is possible (same pole count, same mounting), but the circuit protection rating must match the load and cable size; the panel's coordination study would need revisiting.
