WATSNB-63/4PCR_Schenider_PRODUCT_吉林易择科技技术发展有限公司

The Schneider Electric WATSNB‑63/4PCR is a dual power automatic transfer switch designed for three‑phase low‑voltage power distribution systems. It is used to automatically or manually transfer electrical load between two independent AC power sources (such as utility mains and a backup generator) to maintain continuity of supply for critical loads. The 4‑pole configuration switches all three phases plus neutral for complete isolation and safety. Auxiliary contacts are provided for remote status indication and integration with external control or monitoring systems.
