Automatic transfer switch 630 A, 4-pole

Overview

Automatic transfer switches (ATS) monitor the normal supply and, on failure, transfer the load to an alternative source such as a generator, then transfer back when the normal supply is restored. Selection depends on the rated current and voltage, number of poles (a 4-pole unit also switches the neutral), utilisation category, short-circuit withstand rating and the controller functions required.

Typical applications

• Generator standby changeover for buildings
• Dual-supply changeover for critical loads
• Pump stations and telecoms sites
• Hospitals and data rooms
