5410
Measurement of RCD trip time Conducting testing of
rated residual non-operating currents at × 1/2
Range, measuring RCD trip time at × 1 and × 5
Ranges. • Measurement of trip out current Measuring
trip out current by varying current automatically. •
Remote Test Enabling a user to hold the Test Leads
with his both hands by locking the Test Button.

5406A
Custom microprocessor controlled for highest
accuracy and reliability. • 3 LEDs for checking
correct wiring status. • 0 and 180 degree phase
angle switch permits quick tests and consistent
readings. • Digital read-out of tripping time. •
Constant current source circuitry ensures that a
fluctuating mains voltage does not affect the
accuracy of readings. • Large display readout.

 |
5402D
Accurate digital readout of tripping time. • Two
neon lamps give quick check for correct wiring. •
Compact, lightweight and simple to operate. • Zero
cross circuitry permits testing at 0 and 180 degree
portion of sine wave. At these two tests minimum
(best) and maximum (worst) trip times will be
displayed.
