The PME-500-TR can be connected to any AC supply between 100 and 240V. The unit is also powered
by internal rechargeable batteries that provide 10-hour operation time, allowing to work also when no
AC supply is available. The equipment is provided with special test leads that have a multi-pole
connector. Measurement of the contact resistance of each main pole is performed automatically, with
a test current of 10 A and a resolution of 0.1 µΩ.
All connection elements are located on the front panel. The test connection inputs are duplicated, as
the equipment is supplied with special testing cable leads and there are also 4 mm input taps, with
which any other cable can be used. The software EuroBreaker Basic is supplied with the equipment.
This software enables to download, print and export to MS Excel-readable format the test results
previously saved in the unit.
All the features contained in the equipment, such as manual control via the touch screen panel, an
internal battery supply, a built-in printer and having a clear and easy to operate system, make the
PME-500-TR the most advanced equipment within its category to test circuit breakers. The unit is
enclosed in an airtight, IP67-rated waterproof case.
• Evaluates the synchronism between the circuit breaker
poles.
• Determines the maximum currents, opening and closing
times, simultaneously in both coils.
• Evaluates the state of the substation’s auxillary batteries
by graphically showing the coil consumption.
• Immediately displays and prints test results, both
numerically and graphically.
• Automatically calculates the contact resistance in the
three chambers.
• Travel, speed & acceleration analysis with the optional
PME-TCE plug-in module.
• 3 timing inputs for the three main contacts, 0.1 ms
resolution.
• 2 isolated auxiliary binary inputs, with a capacity for dry
contacts or voltage signals up to ±360 V AC/DC, 0.1 ms
resolution.
