DC Surge Protective Device (DC SPD) — C40 Series (48V / 220V / 500V / 600V / 1000V)
The C40 series DC surge protective device (SPD) is engineered for photovoltaic DC buses and other DC networks. It uses installazione in parallelo to provide reliable surge suppression without affecting normal system operation.
Caratteristiche principali
- Wide clearance & creepage distance; withstands high voltage; suitable for high-altitude areas.
- Pluggable modular cartridge; standard 35mm DIN-rail mounting.
- High-quality lightning-proof components for stable performance.
- Hot-melt + over-current dual protection circuit.
- Status window: green = normal, red = replacement required.
- Low residual voltage, fast response <25ns, strong discharge capability.
- Opzionale remote signaling contact for SCADA/BMS.

FAQ
Which systems is the C40 series designed for?
Photovoltaic DC buses and other DC networks from 48V to 1000V. Select the model by matching Uc.
How do I choose among C40-48 / 220 / 500 / 600 / 1000?
Choose by the max continuous voltage Uc of your DC bus, then verify surge ratings (In/Imax) and target a low Su.
Where should the SPD be installed?
Install at the DC combiner/distribution panel with parallel wiring, short leads, and a reliable PE bar. Follow the diagram.
Is the module replaceable and is remote signaling available?
Yes. The cartridge is pluggable for quick replacement; an optional alarm contact can be wired to SCADA/BMS.
What environmental and wiring requirements apply?
Temperatura di esercizio −40°C ~ +80°C, cross-section of L/N ≥10mm², recinto IP20.
How should surge protection be coordinated?
Coordinate with upstream over-current protection (e.g., DC fuse/breaker) and inverter limits to ensure selectivity and safety.
