WATSNB-160/160.3CBR_Schenider_PRODUCT_吉林易择科技技术发展有限公司

The Schneider Electric WATSNB‑160/160 .3CBR is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It facilitates reliable switching of electrical loads between two independent AC power sources, such as utility mains and a standby generator. The device automatically detects loss or restoration of power on the main source and transfers the load to the alternative source to maintain continuous power for critical loads. The 3‑pole configuration switches the three phase conductors (L1, L2, L3) without switching neutral, making it appropriate for applications where neutral transfer is not required. Auxiliary contacts provide remote indication of the switch position and integrate with control or monitoring systems. Mechanical or electrical interlocking ensures that both sources cannot be connected simultaneously, enhancing safety.
