Breaker Analyzer | MT-300B

Features:

It can detect and show the open or closed position of 12 independent channels (on / off contacts). This makes it easier for the user to check the cable connection.

The device can store up to 50 test results.

The widescreen LCD (320 x 240) provides a reflection or black screen when working under the sun.

It gives the measurement results and graphical representation on the same screen.

The coil voltage can be cut off automatically after the circuit breaker has been started.

Thanks to the adjustable voltage source, the smallest opening voltage of the coil can be tested.

It can perform of ‘open’, ‘closed’, ‘closed-open’, ‘open-closed’ and ‘open-closed-open’ tests.

Can perform parameter measurements of vacuum breakers (single coil).
