So far it is working flawlessly. Load pulls 50-55 amps, depending on voltage, so I am way oversized, maybe. We will see, as others feel the amp rating is overrated. Depending on what my other loads are during the day, my dump load will run for several hours each day. Relay only gets slightly warm. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/146549759-relay-120a-12v-continuous-duty-spst-4-pin-high-power](https://www.desertcart.com.ar/products/146549759-relay-120a-12v-continuous-duty-spst-4-pin-high-power) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-17*
