Made in United States. Manufactured by Functional Devices, Inc. Review: NICE PRODUCT - This device works as advertised. I use it on a 12V fridge that has an AC powered electronic temp control. When I turn off my inverter the device shuts off and routes 12V power to fridge and simultaneously disconnects my temp control loop so the fridge keeps running. Turn the ac back on and temp control is restored with no interruption in cooling (except the contents of fridge are colder) . The device, when on, runs very cool, it is quiet when functioning. Wiring diagram was easy to interpret. The body of the unit is pretty tough. I like the post and nut mounting style as this makes it useable as an add on to existing circuits. Indicator light tells you when AC is present and unit is on in the mode that you wired it for. Review: Will work with line voltage or low voltage. - I had situation where I wanted to add LED strip lighting in a pantry closet but the only power was a three way switch. However, power was at the other three way switch and it was nearly impossible to run a wire to the nearest power outlet. I did some wiring diagrams and I was pleasantly surprise to find this already made relay all encased for easy and safe wiring. I ordered two of them but after a little head scratching only one was needed using the NC and NO contacts What it solves is when the 3 way switch is operated from the other distant switch, the power changes to the other side of the switch I'm using for power. The relay, when it operates, brings voltage to the load on the NO contacts, and when the power is switched over to the other side of the 3 way switch, the relay has no power, therefore the power connects through to the NC contacts. The only little issue is when the power is momentarily dropped as the relay operates, the motion sensor turns on as a default when power is first applied. It only happens when the distant 3 way switch is used and after 30 seconds, the LED light turn off. Very acceptable. ## Features - 10 amp spdt - 10-30 vac/dc/120 vac coil - Sold as each ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LESCI2 | | Best Sellers Rank | #22,768 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #9 in Electromechanical Relays | | Brand | Functional Devices | | Brand Name | Functional Devices | | Coil Resistance | 28 milliohms | | Coil Voltage | 120 volts | | Connector Type | Wired | | Contact Current Rating | 10 A | | Contact Material | Silver | | Contact Type | Normally Closed | | Current Rating | 10 A | | Customer Reviews | 4.7 out of 5 stars 491 Reviews | | Item Weight | 4.64 ounces | | Manufacturer | Functional Devices, Inc | | Maximum Switching Current | 10 A | | Maximum Switching Voltage | 120 volts | | Minimum Switching Voltage | 120 volts | | Model | RIBU1C | | Mounting Type | Track Mount | | Number of Items | 1 | | Number of Packs | 1 | | Number of Terminals | 1 | | Operation Mode | Automatic | | Part Number | RIBU1C | | Specification Met | UL | | UPC | 094236992130 | | Unit Count | 1 Count | | Wattage | 1200 watts | ## Product Details - **Connector Type:** Wired - **Contact Material:** Silver - **Contact Type:** Normally Closed - **Current Rating:** 10 Amps - **Mounting Type:** Track Mount ## Images ![Functional Devices RIBU1C Enclosed Pilot Relay, 10 Amp Spdt with 10-30 Vac/Dc/120 Vac Coil - Image 1](https://m.media-amazon.com/images/I/71c83m3K9kL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ NICE PRODUCT *by J***E on March 7, 2021* This device works as advertised.
