The Internal current measurement paths are not fused. Current limit protection (fuse or breaker) and appropriate wire sizing should be provided by the user. Currents in excess of 140% of the rated rms currents may cause permanent damage to the current measurement shunts.
An internal protection mechanism is provided for the 2 A shunt to avoid damage due to mis-wiring, but it should not be relied upon in situations where higher than 2 Arms currents are expected.
Refer to the data sheet at www.keysight.com/find/PA2201A for up to date information.
