Compact Type 2 (or 3) DC surge protector - 30 V - Disconnection and AC line cut-off
Part Number: 70125042
DDCN03S-L21YG-30
- DC Power Type 2 (or 3) SPD
- 2-port configuration (series mounting)
- Compact and Cost effective
- In/Imax: 1.5 kA/ 3 kA
- Max. load current: 16A
- Disconnection
- 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".
