 The Megger MPCC230 Pro Circuit Checker is a compact, pocket-sized tester for electricians, verifying socket polarity, voltage, RCD performance, and earth loop impedance. It measures AC TRMS voltage (120-250 V, ±1% ± 3 digits), frequency (42-69 Hz, ±2% ± 1 digit), voltage harmonics (0.8-265 V, ±3% ± 5 digits), 30 mA RCD trip time (Type A, AC, F; ±2 ms ± 2 digits), and no-trip earth loop impedance (0.01-999 Ω, ±2-7% ± 8-10 digits) with low (6 mA) and standard (15 mA) test currents. Features include AUTO RCD testing (x1/2, x1, x5, 180°), touch voltage indication, prospective earth fault current, THD%, and socket polarity checks (detecting no earth, phase-neutral/earth reverse, N-PE >50 V).

The 110 g, IP40-rated device, with CAT II 250 V safety, operates in 5 °C to 40 °C, powered by SuperCap technology. Its 1.7″ TFT color LCD ensures clear visibility, and 64-test storage is accessible via the free Megger MPCC app. Compliant with IEC61010-1 and IEC61326-1, it offers harmonic analysis up to the 50th and an intuitive interface. The kit includes the MPCC230 unit and a one-year warranty, making it ideal for professional circuit diagnostics.
