Operating efficiently within a 5-400V range and supporting loads up to 1000W, it features varistor surge protection and a user-friendly crimp terminal design for quick installation. Ideal for enhancing circuit durability and microcontroller stability in inductive load applications. ## Description Module features: RC absorption circuit is also called RC buffer circuit. It is a circuit structure in which resistors and capacitors are connected in series and connected in parallel with switching devices. It is used to improve the voltage and current waveforms that electronic power devices endure when they are turned on and off. The RC absorption loop module can prevent the induced electromotive force generated at the moment when the inductive load is turned on and off from causing damage to switching devices such as relays and thyristors, prevent electromagnetic interference and increase the anti-interference ability of the microcontroller. Application: This module is suitable for circuits containing inductive loads and switching devices (such as relays and thyristors). When used, the two interfaces of the module are on the two contacts of the relay (such as the common end and the normally open end of the relay), or in parallel with the thyristor. , to avoid damage to relays and thyristors caused by induced electromotive force. Package includes: 5pcs RC Snubber/Absorption Circuit Module ## Features - Applicable Load: Suitable for AC or DC 5-400V inductive load (load less than 1000W) to protect relay contacts or thyristors. - Prevention: Equipped with a varistor to prevent voltage fluctuations and excessive current, ensuring the relay's durability and preventing contact adhesion. - Function: The RC absorption circuit module effectively safeguards relays and thyristors by preventing damage caused by inductive electromotive force during power on/off. It also enhances the microcontroller's anti-jamming capability and prevents electromagnetic interference. - Efficient Absorption: Absorbs induced electromotive force generated by inductive loads, ensuring smooth operation and preventing damage. - Convenient Design: Enjoy the convenience of crimp terminals, making wiring quick and hassle-free, saving you time and effort. - Application: This module is suitable for circuits containing inductive loads and switching devices (such as relays and thyristors). - Package includes: Includes 5pcs RC Snubber/Absorption Circuit Module, offering great value for money. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0CR3HLH94 | | Best Sellers Rank | 354,294 in DIY & Tools (See Top 100 in DIY & Tools) 32 in Furnace Circuit Boards | | Brand | DAOKAI | | Circuit Breaker Type | Standard | | Country Of Origin | China | | Current Rating | 1 Amps | | Customer Reviews | 4.1 4.1 out of 5 stars (13) 4.1 out of 5 stars | | Included Components | 5pcs RC Snubber/Absorption Circuit Module | | Manufacturer | DAOKAI | | Manufacturer Part Number | WE-DA-342 | | Model Number | WE-DA-342 | | Mounting Type | Surface Mount | | Number Of Poles | 1 | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 5.0 count | | Voltage | 400 Volts | ## Product Details - **Brand:** DAOKAI - **Circuit breaker type:** Standard - **Manufacturer:** DAOKAI - **Voltage:** 400 Volts ## Images ![RC Snubber/Absorption Circuit Module,5 PCS Relay Contact Protection Circuit Electromagnetic Anti-Interference Module DC 5-400V Inductive Load Resistance Surge - Image 1](https://m.media-amazon.com/images/I/61v4Oe1UVuL.jpg) ![RC Snubber/Absorption Circuit Module,5 PCS Relay Contact Protection Circuit Electromagnetic Anti-Interference Module DC 5-400V Inductive Load Resistance Surge - Image 2](https://m.media-amazon.com/images/I/610g14sHtzL.jpg) ![RC Snubber/Absorption Circuit Module,5 PCS Relay Contact Protection Circuit Electromagnetic Anti-Interference Module DC 5-400V Inductive Load Resistance Surge - Image 3](https://m.media-amazon.com/images/I/51JGMnkCP1L.jpg) ![RC Snubber/Absorption Circuit Module,5 PCS Relay Contact Protection Circuit Electromagnetic Anti-Interference Module DC 5-400V Inductive Load Resistance Surge - Image 4](https://m.media-amazon.com/images/I/6177fR5eHNL.jpg) ![RC Snubber/Absorption Circuit Module,5 PCS Relay Contact Protection Circuit Electromagnetic Anti-Interference Module DC 5-400V Inductive Load Resistance Surge - Image 5](https://m.media-amazon.com/images/I/61ZDy8OT5EL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple to use *by on Reviewed in the United Kingdom 16 January 2026* Easy to use and cuts down switch and relay contact arcing ### ⭐⭐⭐⭐⭐ Seems great so far! *by on Reviewed in the United States 20 May 2026* So far it’s working great. Helps get my vent fan working with a motion switch ### ⭐⭐⭐⭐ Good snubber but the varistor is more suitable for 220VAC *by on Reviewed in Canada 18 October 2024* This is a useful snubber with good build.The only point is that the varistor type is 10D471K (10mm disk, with 470V +/-10% clamping voltage, 45-67mJ dissipation). This rating is typically used for 220/240VAC lines. For the North American market a 10D271K varistor is the better choice to effectively absorb transient energy for equipment operating at 110/120VAC voltage. The RC snubber is composed of a 220 Ohms/1Watt carbon resistor paired with a 100nF/630V film capacitor. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/652444360-rc-snubber-absorption-circuit-module-5-pcs-relay-contact-protection](https://www.desertcart.com.pa/products/652444360-rc-snubber-absorption-circuit-module-5-pcs-relay-contact-protection) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-01*
