Specification

• Custom microprocessor controlled for highest accuracy and reliability.
• 3 LEDs for checking correct wiring status.
• 15mA LOOP measurement:
LOOP impedance 2000© range measurement is carried out with low test current (15mA). The current will not cause tripping out involved RCD even the one with the lowest nominal differential current (30mA).
• Model 4120A has the automatic RCD (ELCB) lock device. There is no need to by-pass most passive RCD's at distribution boards when conducting LOOP or PSC tests.
• Direct reading of Prospective Short Circuit Current (PSC) and earth fault current.
• Safe voltage measurement function.
• Large custom digital display readout on all models.
• Measures low loop resistances (resolution of 0.01©)
• Automatic lock-out if test resister overheats.
• Large custom digital display readout.
• Visual indication of reversed phase and neutral wiring at socket.
• Designed to IP54 Rating
• Complies with IEC 61557
