Great purchase! Review: Low quality - Used a number of CT clamps before and have to say these are low quality. Tried to work with support which did little to nothing to help resolve the matter so just sent them back. ## Features - All-Scenario No-Power-Cut Current Monitoring：scenarios like live retrofits in substations/workshops, online monitoring for motors/frequency converters, post-construction current metering in buildings, and temporary testing during power maintenance—avoiding downtime losses while realizing flexible current measurement and signal transmission (compatible with ammeters, PLCs). - Split Core Structural Advantage - Detachable core design eliminates the need for cable threading or power-off during installation, solving the pain point of difficult disassembly and assembly of traditional closed transformers, especially suitable for fixed cables in cable trays or existing circuits.​ - Stable Accuracy and Broad Compatibility—Featuring accuracy classes ranging from 0.5 to 1, with a 24mm inner diameter, it meets daily current measurement needs. Supporting a rated current range of 50A to 1000A, it is compatible with low-voltage circuits (AC 0.4kV and below) and can be paired with common monitoring devices such as ammeters, energy meters, and PLCs. - Effortless Installation & Disassembly - No complex tools required, the core can be closed and fixed quickly by hand or with simple tools, reducing installation time to within 5 minutes; it is also easy to disassemble, making it convenient for temporary use or later maintenance.​ - Stable operation—achieves electrical isolation between high-current main circuits and low-current auxiliary circuits, effectively preventing high-voltage hazards from affecting monitoring equipment and personnel, and proving highly effective in industrial and building electrical applications. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B91R55TS | | Best Sellers Rank | #69,187 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #40 in Power Transformers | | Brand Name | nodehawk | | Current Rating | 200 Amps | | Customer Reviews | 3.4 3.4 out of 5 stars (26) | | Included Components | one meter line | | Item Dimensions D x W x H | 2.13"D x 1.26"W x 2.56"H | | Item Weight | 229 Grams | | Manufacturer | nodehawk | | Maximum Frequency | 60 Hz | | Minimum Frequency | 50 Hz | | Model | 3395597999613 | | Mounting Type | Surface Mount | | Part Number | 3395597999613 | | Power Source | Corded Electric | | Specification Met | CE, UL | ## Product Details - **Brand:** nodehawk - **Current Rating:** 200 Amps - **Mounting Type:** Surface Mount - **Power Source:** Corded Electric - **Product Dimensions:** 2.13"D x 1.26"W x 2.56"H ## Images ![AC Current Sensor Transformer, Core Current Transformer Coil Sensor for 200A Amp Energy Meter - Image 1](https://m.media-amazon.com/images/I/71bY3ph-R+L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great purchase *by N***S on November 6, 2024* Low price, but works perfectly. Great purchase! ### ⭐ Low quality *by K***I on January 10, 2026* Used a number of CT clamps before and have to say these are low quality. Tried to work with support which did little to nothing to help resolve the matter so just sent them back. ### ⭐⭐⭐ 60 Hz Buzz *by A***D on November 2, 2025* The price is great. The build quality seemed good at first. I received exactly as a described a 200A : 5A current sensor CT clamp (a current ratio of 40). However they buzz at 60hz, not all the time, but often enough. They'll buzz, go quiet, then just as you think you can think again. As I understand this is a 60 Hz vibration and due to some gap in the internal metal to plastic connection -- it sounds just like a loud transformer with the same hum / buzz. ## Frequently Bought Together - AC Current Sensor Transformer, Core Current Transformer Coil Sensor for 200A Amp Energy Meter - GV23AT 3 Phase AC Ammeter Tester Meter Generator Three-p Digital Display Current Meter - PZCT-02 Split Core Current Transformer Coil Sensor for 100A Amp Energy Meter --- ## 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.nz/products/471103583-ac-current-sensor-transformer-core-current-transformer-coil-sensor-200a](https://www.desertcart.nz/products/471103583-ac-current-sensor-transformer-core-current-transformer-coil-sensor-200a) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-06*
