  • Complete Protection FunctionThis switch has multiple protection functions, including short circuit, overload, phase loss, and under voltage protection. The protective cover helps reduce accidental contact with internal electrical components.

Description

Q1: Does it have a manual override switch? A: Yes. This 2P transfer switch supports Auto and Manual modes. In Manual mode, you can operate the handle to select between power source I and power source II. Q2: Can it work with solar power systems? A: Yes. When properly wired, it can switch between utility power and a solar inverter, generator, or other backup power sources. Q3: What is the maximum load capacity? A: This 2P transfer switch is rated for AC 110V and up to 63A. Ensure your system load does not exceed this capacity for safe operation. Q4: Can it be used outdoors? A: Yes, but it must be installed inside a waterproof distribution box or protective enclosure. The transfer switch itself is not waterproof, so outdoor use requires proper protection. Q5: Is it easy to install? A: Yes. Designed for DIN rail installation, it fits standard distribution boxes. Installation should be performed by a qualified electrician for safety. Q6: Does it switch automatically during power failure? A: Yes. In Auto mode, it detects abnormal primary power and switches automatically to the backup power source. Q7: Can it work with a generator? A: Yes. When connected correctly, it can switch between utility power and a generator. Q8: What applications is it suitable for? A: Suitable for home backup power, solar systems, generators, RV power systems, and other dual-power switching setups. Life for Convenience, Life for Happiness.
