HCDC AC120V 15A Automatic Transfer Switch (NEMA 5-15P/R) – IP68 Outdoor-Ready

Overview

The HCDC HD060 Automatic Transfer Switch is a compact, mountable relay designed to seamlessly switch between AC INPUT 2 (utility or shore power) and AC INPUT 1 (inverter or generator) to the connected load. This design helps you manage power sources without manual intervention and keeps essential devices powered when one source drops.

When AC INPUT 2 is live, the load is supplied from INPUT 2; if INPUT 2 loses power, the switch automatically routes the load to INPUT 1. The transfer happens in under 0.03 seconds, a brief moment that most smart devices and computers won’t notice.

Durable, safe, and maintenance-friendly

• Four high-power SPST relays reduce arcing and improve reliability during transfers.
• Live and Neutral are switched together; Ground wires are internally bonded, simplifying wiring and safety.
• IP68-rated enclosure with a PC (polycarbonate) case, silicone seals, and 304 stainless steel hardware stands up to indoor or outdoor use.

What’s included and how it fits your setup

• AC INPUT 1 cable length: 19 inches (0.5 m) with a US standard NEMA 5-15P plug.
• AC INPUT 2 and AC OUTPUT cables: each 19 inches (0.5 m) long, 14 AWG, three conductors.
• Designed for 90–135V AC operation at 50/60 Hz, with a maximum current of 15 A.

Real-world applications

Use the HD060 to manage essential electronics in a home office, media center, or workshop where you switch between a utility feed and a generator or inverter. The quick transfer supports smart devices and computers that need uninterrupted power during source changes. Outdoors, it’s well-suited for cabins, RV setups, or weather-exposed installations where robust housing matters.
