Misopily AC120V 15Amp Automatic Transfer Switch NEMA 5 15P R Inline Relay for Generator Inverter Utility Power IP68 Waterproof Case 19 Inch Cable

This automatic transfer switch provides seamless switching between two AC power sources, such as utility or shore power and inverter or generator, ensuring uninterrupted operation for your connected devices in both residential and commercial applications.

Designed for an operating voltage range of AC 90 to 135V at 50 or 60Hz and supporting a maximum current of 15 amps, this unit features a fast transfer time of less than 30 milliseconds, which is suitable for most sensitive electronics and smart devices without causing operational disruptions.

The internal mechanism incorporates four high-power SPST relays that switch both live and neutral wires simultaneously, effectively minimizing the risks associated with high inductive load arcing and providing enhanced safety and reliability in demanding environments.

Constructed with an IP68 waterproof enclosure made from flame retardant polycarbonate and sealed with silicone rubber, this transfer switch is suitable for indoor or outdoor installation, offering durable protection against dust, water, and harsh weather conditions.

The device includes three 19 inch long cables for AC input and output, with input 1 featuring a US standard NEMA 5-15P 3-prong plug and all cables built with 14AWG wire for secure, efficient, and stable electrical connections in various installation settings.

All ground wires from both inputs and the output are internally connected and remain unaffected by switching, while external screws are made from 304 stainless steel to ensure corrosion resistance and long-term durability in a variety of environments.
