WATSNB-32/4PCR_Schenider_PRODUCT_吉林易择科技技术发展有限公司

The Schneider Electric WATSNB‑32/4PCR is a dual power automatic transfer switch designed for three‑phase low‑voltage power distribution systems. It provides reliable switching of electrical loads between two independent AC power sources (such as utility mains and a standby generator), ensuring continuity of supply for critical equipment and circuits. The 4‑pole construction switches all three phase conductors plus neutral, offering complete load isolation and enhanced safety. The switch supports both automatic and manual mode, with auxiliary contacts for remote status indication and integration into control or monitoring systems.
