The WCQ2G-100 4P Dual Power Automatic Transfer Switch complies with GB/T 14048.11 and IEC standard Part 6-1 for multifunction equipment and low-voltage switchgear. These certifications confirm the product meets recognized safety and performance benchmarks for automatic transfer switching equipment in low-voltage distribution systems.
The WCQ2G-100 4P Dual Power Automatic Transfer Switch (ATS) is a micro-intelligent changeover switch that automatically transfers power between main and backup supplies. It handles residential and light commercial backup applications where uninterrupted power is needed during grid outages or voltage drops.
Built for PZ30 distribution boxes with DIN rail mounting, this 100A 4-pole switch maintains continuous power delivery during outages or voltage instability. The 4-pole design controls all live conductors and the neutral line, providing complete circuit isolation during transfer.
Operating at AC 400V, 50Hz/60Hz, the ATS continuously monitors the primary power source. When a failure is detected, it switches to the backup supply to maintain stable operation. The response time is fast enough to keep connected equipment running without reset.
Suitable for residential, commercial, and light industrial settings, the WCQ2G-100 ATS combines a durable enclosure, reliable switching, and straightforward installation. It fits emergency power setups where a generator or secondary grid connection serves as the backup source.
The unit integrates a transfer switching equipment (TSE) module and a controller in a single compact housing. It supports two operating modes: automatic, where the controller monitors voltage and triggers the switch, and manual, where the operator selects the power source directly on the device.
Whether installed in homes, offices, communication base stations, or security monitoring rooms, this 100A 4P automatic transfer switch provides stable automatic energy management at the distribution board level. It is suited to any installation where power continuity is critical and manual intervention during an outage is impractical.
