The WATSNB‑630/630‑3P is a dual power automatic transfer switch designed for three-phase power distribution systems. It ensures continuity of supply by automatically switching between two independent sources, such as utility mains and a backup generator. This model features a 3‑pole configuration, switching the three phase conductors, and is rated for high-current applications up to 630 A. Typical installations include backup power systems, critical infrastructure, and industrial distribution boards.
