Description
MCL-4000F 3CT Method Clamp Tester
The MCL-4000F 3CT Method Clamp Tester is designed to measure AC leakage current in three-phase, three-wire and four-wire power systems. Its 3CT measurement method allows each phase conductor to be clamped individually, making it particularly useful where clamping all phase conductors together is difficult.
The instrument measures AC leakage current from 0 to 2000 mA and load current up to 800 A, with an accuracy of ±1.0% of reading ±5 digits. It also features a 130 Hz low-pass filter for high-frequency noise rejection and a DC 100 mV full-scale output for connection to a recorder.
The MCL-4000F uses three CT sensors for three-phase, three-wire systems. For three-phase, four-wire systems, a fourth CT sensor is required and is available separately as the MCL-4000F-NCT.
