Simultaneous measurement for the 3 main contacts (open/ closed) and 2 auxiliary contacts, including pre-insertion resistors (if present in the circuit breaker)
Evaluates the synchronism between the circuit breaker poles
Determines the maximum currents, opening and closing times, simultaneously in both coils
Fully analyze circuit breaker’s performance by measuring main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes
USB PC interface/USB Flash drive interface
Store up to 200 test. records and 100 test plans internally
