4.1 

Tripping Characteristics 

The electronic circuit breaker verifies that the output current is greater than the 

nominal current setting. As soon as the output current exceeds this nominal 

current, the channel is switched off. The trip time depends on the magnitude of 

the overcurrent. The figure below depicts the respective trip times:
