It may not protect whatever component only wants to see 3.2 amp. **Q: The specs for this 10 a breaker says current 3-50 a; rating 10 a. i thought that the circuit breaker would open over 10 a ? 50 a is too much!** A: It's rated at 10 a for ac **Q: Will this work in a predator 4000 watts generator replacing the 13amp breaker** A: I am not 100% sure, but I don't see why not. It's pretty close in specs, so should work. The 15Amp max is a little above your 13Amp, therefore if you have 15Amp wiring, breaker, etc., it should be okay. But that's only my opinion. **Q: diameter of mounting hole required? it seems this was asked but no tangible replies...** A: 3/8" hole ## Frequently Bought Together - RKURCK 125-250V AC 50V DC Push Button Circuit Breaker 20Amp Thermal Overload Protector L1 Series Manual Reset Thermal Circuit Breaker 20A - HQRP On-Off Paddle Switch Compatible with Sears Craftsman 137 Series Table Saw & Drill Press 0LWG 27A1 0LWC 0LVW, UL Listed - HAKATOP SW7B On-Off Toggle Switch 2 Prong for Delta, Aftermarket Replaces Parts Ryobi Table Saws Drill Press Delta 489105-00 46023 Switch --- ## 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.jp/products/139497496-125-250v-ac-50v-dc-push-button-circuit-breaker-20amp](https://www.desertcart.jp/products/139497496-125-250v-ac-50v-dc-push-button-circuit-breaker-20amp) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-31*
