Designed for professional-grade electrical protection, it supports multiple relay ports (NO, NC, COM) to control external circuits automatically. Compact and robust, it operates reliably across a wide temperature range and frequency spectrum, making it an essential tool for preventing electrical overloads in advanced setups. ## Description Specification:Type: 5A 12V Relay ModuleWorking voltage: DC12VWorking current: <20MAOperating frequency range: 20Hz-400HzOutput mode: switch signal outputMaximum detection wire diameter: 5.2mmMounting hole: hole diameter is 3mm, hole pitch is 52.5mmOperating environment: -40℃ - 85℃Current detection range: AC0.3A-5ABoard size: Approx. 38 * 44mm / 1.5 * 1.7inWeight: Approx. 27gPackage list:1 * ModuleFunctions:Current detection resolution can change the parameter of resistance parameters.Output over-current switching signal output.Over-current signal setting critical point is adjustable.Board Description:VCC: Operating voltage positive;GND :Operating voltage negative;NO: Normally open, the relay pulls before the NO and COM disconnect, short-circuit after the suction;COM: common, relay common interface;NC: Normally closed, the relay before the NC and COM short-circuit, after pull off. Using Instructions:By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment can reduce the detection current.As bellows:1. Measured the wire through the current transformer , connect VCC and GND to DC12V power supply; ## Features - 【Features】The sensor module is 5A over-current protection sensor module. - 【Working Principle】5V overcurrent protection uses a current transformer to collect the AC signal to achieve the relay over-current signal output within 0-5A. - 【Application】The relay module is relay pull while over-current, relay released while not over-current. - 【Function】DC current sensor module users can use the relay COM, NC, NO three ports to control the external circuit on and off, in order to achieve over-current protection. - 【Practical】The current sensor over-current signal setting critical point is adjustable. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09L69V661 | | Brand | Kuuleyn | | Contact Current Rating | 5 Amps | | Contact Type | Normally Closed | | Contact current rating | 5 Amps | | Contact type | Normally Closed | | Country Of Origin | China | | Current Rating | 5 Amps | | Current rating | 5 Amps | | Item Weight | 27 Grams | | Manufacturer | Kuuleyn | | Manufacturer Part Number | Kuuleynofg4zam971 | | Maximum Switching Voltage | 12 Volts | | Maximum switching voltage | 12 Volts | | Operation Mode | Automatic | | Operation mode | Automatic | ## Images ![Sensor Module, Relay Module, DC Current Sensor Module, Current Sensor, 5V 0-5A AC Current Detection Sensor Module Relay Module Overcurrent Protection - Image 1](https://m.media-amazon.com/images/I/61-SyK2X1tS.jpg) ![Sensor Module, Relay Module, DC Current Sensor Module, Current Sensor, 5V 0-5A AC Current Detection Sensor Module Relay Module Overcurrent Protection - Image 2](https://m.media-amazon.com/images/I/61i8P2MO2pS.jpg) ![Sensor Module, Relay Module, DC Current Sensor Module, Current Sensor, 5V 0-5A AC Current Detection Sensor Module Relay Module Overcurrent Protection - Image 3](https://m.media-amazon.com/images/I/61UaBVmxiOS.jpg) ![Sensor Module, Relay Module, DC Current Sensor Module, Current Sensor, 5V 0-5A AC Current Detection Sensor Module Relay Module Overcurrent Protection - Image 4](https://m.media-amazon.com/images/I/71JyTAarRhS.jpg) ![Sensor Module, Relay Module, DC Current Sensor Module, Current Sensor, 5V 0-5A AC Current Detection Sensor Module Relay Module Overcurrent Protection - Image 5](https://m.media-amazon.com/images/I/61YEY98F-5S.jpg) --- ## 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://slovenia.desertcart.com/products/382873529-sensor-module-relay-module-dc-current-sensor-module-current-sensor](https://slovenia.desertcart.com/products/382873529-sensor-module-relay-module-dc-current-sensor-module-current-sensor) --- *Product available on Desertcart Slovenia* *Store origin: SI* *Last updated: 2026-08-18*
