The CW2 series supports Modbus‑RTU, Profibus, DeviceNet, CAN bus and Ethernet via the CN1DP and CN1EG adapters.
It provides instantaneous or timed under‑voltage release with adjustable delay times from 0.5 s to 10 s, used for PV grid‑connected applications.
The breakers are offered in three‑pole (3P) and four‑pole (4P) versions.
Yes, versions are available for temperatures down to –40 °C, suitable for humid‑tropical (TH) conditions.
