Description

Dual Power Automatic Transfer Switch – 4 Pole, 63A (YRO YRQ4PC-63/4P) | PC Class ATS

Protect your three-phase operations from power interruptions with the YRO YRQ4PC-63/4P Dual Power Automatic Transfer Switch — a PC-class (Power Circuit) ATS engineered for fast, fully automatic switching between two three-phase power sources such as mains and solar inverter, or mains and generator. Compliant with IEC 60947-6 and CE certified, this 4-pole unit is purpose-built for three-phase DIN-rail distribution boards in commercial, industrial, and solar energy installations.

The YRQ4PC-63/4P features clearly labelled four-pole input terminals for both Source 1 (L1|L2 + L3|N1) and Source 2 (L1|L2 + L3|N1), with a dedicated four-pole load output (L1|L2 + L3|N), and a robust sliding handle mechanism supporting both AUTO (fully automatic) and MANU (manual override) switching modes. In AUTO mode, the device continuously monitors both three-phase power sources and instantly transfers the load the moment a supply failure is detected — with zero user intervention required. The built-in dual LED indicator (Green = Source 1 active / Red = Source 2 active) gives instant visual confirmation of which power source is currently supplying the load.
