Product details

The IP40 enclosure and IK07 impact rating suit panel-mount installations where splash protection is not required.

This allows selective coordination in a distribution panel — downstream faults are cleared by this MCCB while upstream breakers remain closed, keeping other circuits live. Category A utilisation means it is not intended for current-limiting applications but for general distribution.

Environmental and electrical ratings

Relative humidity 0–95 %. Power dissipation is 3.8 W per pole.
