Compact Type 2 (or 3) DC surge protector - 65 V - Monobloc

DDCN06S-21YG-65
Part Number 70134052
DDCN06S-21YG-65
  • DC Power Type 2+3 SPD
  • 2-port configuration (series mounting)
  • Compact and Cost effective
  • In/Imax: 2 kA/6 kA
  • Max. load current: 25A
  • Disconnection + AC line cut
  • Remote signaling
  • EN 61643-11, IEC 61643-11 compliance

The devices of the DDCN series are SPDs of type 2+3 and designed for use in applications with nominal voltages of 24 or 48 Vdc, such as sensitive sensors, control systems in industry, etc.. The DDCN can be used as 1-port or 2-port SPD. The generously dimensioned connection cage with its capacity for cable cross-sections of up to 10 mm² ensures practical installation. The 2-pole DC surge arresters are designed for DIN rail mounting and occupy only 1 HP. The certification as type 2 + 3 was based on tests with similar parameters, which are also used for AC SPDs, but also according to the draft of P DIN IEC 61643-41 "Surge protective devices for use in low-voltage DC installations - Requirements and tests".
