Review: Die im Lieferumfang enthaltenen Batterien sind bereits ausgelaufen... :( schlecht, wenn Ware so lange rum liegt ohne nachkontrolle Review: Lo compre principalmente por qué permite hacer mediciones sin contacto con las partes energizadas basta con colocar la pinza sobre el aislamiento de los cables para que haga la medición de la secuencia de fases, cuenta con imanes qué permiten fijarlo. Lo recomiendo principalmente por la seguridad que birnda ## Features - Displays graphical phase orientation - Checks phase sequence and phase status - Tests up to 600VAC and displays graphical phase orientation on the large LCD - Double molded durable housing - Easy to use alligator clips with wide jaws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001AGTXY2 | | ASIN | B001AGTXY2 | | Batteries | 1 Product Specific batteries required. | | Best Sellers Rank | #154,215 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #215 in Circuit Testers | | Brand Name | Extech | | Color | 480400 | | Customer Reviews | 4.7 4.7 out of 5 stars (310) | | Customer reviews | 4.7 4.7 out of 5 stars (310) | | Date First Available | 1 January 2024 | | Global Trade Identification Number | 00793950484005 | | Is Discontinued By Manufacturer | No | | Item Dimensions | 6.9 x 3.2 x 13 centimeters | | Item Weight | 0.14 Kilograms | | Item model number | 480400 | | Manufacturer | Extech | | Manufacturer | Extech | | Maximum Operating Voltage | 600 Volts | | Measurement Type | Phase Sequence Indicator | | Minimum Operating Voltage | 9 Volts | | Model | 480400 | | Power Source | Battery Powered | | Product Dimensions | 6.86 x 3.18 x 12.96 cm; 140 g | | Specification Met | CE | | Style Name | 480400 | | UPC | 798256210433 793950484005 | | Upper Temperature Rating | 150 Degrees Celsius | ## Product Details - **Brand:** Extech - **Colour:** 480400 - **Item weight:** 0.14 Kilograms - **Power source:** Battery Powered - **Style:** 480400 ## Images ![480400 Phase r - Image 1](https://m.media-amazon.com/images/I/71-3o+jVj-L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will this work on 4/0 wire?** A: Yes I personally used it on 750MCM which is 5 times the diameter of 4/0. This is a great phase rotation meter. **Q: Does it work on 480-V delta and wye systems?** A: Yes. It has worked perfectly on all systems and all voltages up to and including 480 for us. Excellent tool and much safer. **Q: Will this work on the output of a VFD?** A: It should as long as the VFD is running (being commanded to go a direction at 50-60 HZ) **Q: Can this be used on single phase 240 volt service?** A: Hi, phase sequence is only used to determine the correct phasing of the 3 phase supply. You need not use this device for single phase at all. You only need a volt meter to ensure that the supply is in order in terms of L N E. ## Customer Reviews ### ⭐ Review *by D***M on 3 September 2021* Die im Lieferumfang enthaltenen Batterien sind bereits ausgelaufen... :( schlecht, wenn Ware so lange rum liegt ohne nachkontrolle ### ⭐⭐⭐⭐⭐ Review *by A***A on 8 February 2026* Lo compre principalmente por qué permite hacer mediciones sin contacto con las partes energizadas basta con colocar la pinza sobre el aislamiento de los cables para que haga la medición de la secuencia de fases, cuenta con imanes qué permiten fijarlo.
