In short circuit laboratories high voltage equipment, for instance a transformer or high voltage switch, is being tested for durability against extreme peak exposures, high voltages and/or high currents.
The MTSA Master Break Switch 1214 is an air blast safety switch to cut the current in case the test object fails doing so properly. The MTSA Master Break Switch 1214 has been specially designed for High Power Labs.
The main advantage of the MTSA Master Break Switch 1214 over conventional safety breakers is that due to its extreme short opening time of 7 ms (less than half a current cycle), it will largely prevent damage to the test object and other components in the test circuit. The MTSA Master Break Switch has a much larger breaking capacity than the test object.
