The WBL551AT03-20 (Clamp Split-Type Leakage Current Sensor) utilizes the phase-difference magnetic modulation principle to measure both DC current and differential current (leakage current). It undergoes 100% thermal aging treatment and high-temperature drift testing to ensure excellent long-term stability.
This clamp split-type sensor features a fully sealed design, low power consumption, and galvanic isolation between the primary and secondary circuits. It also offers strong overload capacity, easy installation, and high cost-effectiveness. Sensors with different input current and output voltage specifications can be customized according to user requirements.
