Three-Phase AC Phase Detector with LED Indicator, Buzzer, and Clip, 60V-600V, 3-Phase AC Voltage, Rotation, Voltage, and Clamp Meter for Breakers,

[Dual Functions] This three-phase AC phase detector has two functions: a display to check whether the phase arrangement is correct or not, and a display to show whether the phase is open or not. This function allows you to easily check the operating status of the circuit and phases. [LED Indicator] The LED indicator is an important feature of this phase detector. If the phase sequence is correct, the LED indicator will turn green and emit an intermittent beep. If the phase sequence is reversed, the LED indicator will turn red and emit a continuous beep. [20Hz-400Hz Measurable Frequency Range] It is easy to use. Suitable for three-phase AC voltage, it can measure frequencies from 20Hz to 400Hz. Simply connect this phase detector to the circuit to measure the phase status, making it ideal for a variety of practical application scenarios. [Clip Included] Safe and Reliable Design. Equipped with a clip that easily contacts the circuit terminals, it ensures safe and reliable measurements. Users can use it with confidence and feel more secure. [60V-600V Three-Phase AC Voltage] Wide voltage testing is the main feature of this three-phase AC phase detector. It can detect three-phase AC voltages from 60V to 600V with excellent performance. It can accurately test and display the phase status under both low and high voltage conditions.
