The 1200A-3PH is a three phase injection system providing
commissioning and maintenance engineers with a flexible
system for testing protective systems. It has an easy to
understand panel layout and a simple user interface. The
status of every function can be seen at a glance, and there
are no complex menus to navigate.
Each loading unit has two output taps to allow for a range of
load impedance. Each phase is isolated and can be
configured to either give a maximum of 1200A at 3.5V or
600A at 7V. Three true RMS metering ranges are provided,
allowing the full scale of the meter and trip level to be set
independently of the selected output.

An auxiliary metering input is provided and can measure
voltage, current, frequency, and the phase between any of
the current outputs and an external voltage or current.
The timing system is very flexible without compromising ease
of use, allowing trip times, reset times and reclose times to be
quickly measured to a high degree of accuracy. Two
independently isolated contact inputs are provided, and the
timing system may also be used as a stand-alone timer.
The 1200A-3PH can be use to test many single and three
phase devices including:
? Over and under current
relays
? IDMT relays
? Auto-reclosers
? Time delay relays
? Earth fault relays
? Miniature circuit breakers
? Power relays
? Tripping relays
? Thermal relays
