MCBs Type D curve

D Tripping Curve (Characteristic)

  • Ref. BS7671 Apx 3 Fig. 3A6
  • Circuit-Breakers to EN60898-1
  • Energy limiting class 1 or 3 does not apply to D curve MCBs

Note: Doepke D curve MCBs ref DLS6 iD
≤ 40A are rated Icn < 10 kA, 400 Volt AC.
> 40A are rated Icn < 6 kA, 400 Volt AC.
