The Megger TM1600 circuit breaker analyzer measures a circuit breaker’s timing cycle. The timing channels record closings and openings of main contacts, resistor contacts and auxiliary contacts. Since the timing channels are not interconnected, you can take measurements of resistor contacts and series-connected breaker chambers without having to disconnect them.
A built-in program unit permits easy selection of different sequences of breaker control pulses. The delay time between pulses is set on a thumbwheel. The breaker operation unit can be used to control coil currents of up to 25 A. The time values obtained refer to the exact instant at which voltage was applied to the coil, and a built-in printer provides you with a hardcopy printout immediately after measurement.
The TM1600 can be equipped with up to 24 time-measuring channels as required by the user. When more than 24 channels are needed, one or several units can be connected together to get an unlimited number of measurement channels. Modular design also makes it easy to combine the system with the MA61™ Motion Analyzer for up to 6 analog channels. The TM1600 supports communication with the CABA Win™ Breaker Analysis Software. Fully equipped, it weighs only 12 kg (26.5 lbs).
