Solid State Relay Wiring Diagram Solid State Relay Dimension What are the precautions 1. It is strictly prohibited to short circuit the load, as short circuit can damage the product. Please install a semiconductor protection special fast fuse in the main circuit of the load; 2. When the output terminal is closed, there is a risk of electric shock due to incomplete insulation isolation and leakage current. To improve safety and facilitate maintenance, please install isolation components such as contactors, relays, and automatic switches in the load main circuit; 3. If the load current is above 5A, please install a radiator! Please use forced air cooling in places where the ambient temperature exceeds 40 degrees ! Review: Positive experience - Exactly as advertised. Shipped fast enough, packaged well enough and works fine. I used this to run my well pump using a 110V trigger from an electronic pressure switch unit. I wanted to use this to power the well pump as it will be more bullet proof on the amperage running the well pump, though the well pump is only at 4.5 amps. If you have a heavy amp draw you might consider adding a little computer fan to the heat sink and make it more bullet proof to heat. Good little unit, good price and very handy. Review: AA vs AD is a big difference - This controller works perfectly. I made the mistake of ordering the AA model meaning I had to provide AC voltage to switch the relay on. Ooooooops. I really needed the AD version to switch AC using 5v DC logic. I had a spare relay on hand to switch the AC on/off. ## Features - Model: SSR-25AA, single phase Solid State Relay 60A AC to AC control, CE Compliant to EN60950-1 - Input voltage 80-250V AC, Load voltage 24-380V AC, Max load current 25 Amp - Rugged epoxy encapsulation construction, high isolation over than 50MĪ©(500VDC), high dielectric over than 2.5KV, output snubber circuit protection - No EMI/EFI & Low surge by Zero Cross Trigger method, specially suited to control sensitive, capacitive and Non-saturated inductive loads - SSR switches use semiconductor component acts as a switch for the relay, no moving parts inside, no mechanical wear, no action noise, no mechanical failure, and high reliability ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.1 out of 5 stars 52 Reviews | ## Images ![SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A - Image 1](https://m.media-amazon.com/images/I/51MB7um--fL.jpg) ![SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A - Image 2](https://m.media-amazon.com/images/I/51laIzmL2gL.jpg) ![SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A - Image 3](https://m.media-amazon.com/images/I/51v-DvTPt7L.jpg) ![SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A - Image 4](https://m.media-amazon.com/images/I/610IFd5EqAL.jpg) ![SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A - Image 5](https://m.media-amazon.com/images/I/61XqKkoTzJL.jpg) ## Questions & Answers **Q: What is solid state relay ?** A: Solid-state relay is a new type of electronic relay.

I made the mistake of ordering the AA model meaning I had to provide AC voltage to switch the relay on. Ooooooops. I really needed the AD version to switch AC using 5v DC logic. I had a spare relay on hand to switch the AC on/off. ### ā­ Not recommended *by M***S on February 27, 2023* This unit was purchased to control a 20 amp rated heater which doesn't really draw that much. Even though it was being operated below its stated current rating with the heatsink in place, this unit failed after a couple of months. Failure mode was severe overheating resulting in the unit going up in flames. Fortunately circuit breakers tripped before any damage occurred. If you must have a solid state relay, I recommend getting one with a current rating much higher (at least 50%) than your requirements. Better yet, for such high current requirements, there are actual physical relay units available that should be more reliable. ## Frequently Bought Together - SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A - SSR-40AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 40A - SSR-25DA Solid State Relay DC to AC (Input 3-32V DC Output 24-380V AC) with Heat Sink, 25A --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/241212381-ssr-25aa-solid-state-relay-ac-to-ac-input-80](https://www.desertcart.be/products/241212381-ssr-25aa-solid-state-relay-ac-to-ac-input-80) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-18*
