Notes
No upstream protective device
required,as it is the auto-
protected range (150 kA)
1)
Fuse (A gG/gL) for increasing the switching capacity of the motor-protective
circuit-breaker to 100 kA
2)
Please enquire for additional information regarding voltages >400 V and
device combinations with CL-PKZ0.
