C for marine used)
*2: For 2-pole applications, use two poles at both ends.
*3: 4-pole ACBs are not applicable to power distribution IT systems unless N-phase protection is provided.
*4: Setting the instantaneous trip function to NON reduces the rated breaking current to the rated latching current.
*5: Applicable to 3-pole ACBs
*6: For applicability to power distribution IT systems, consult us
*7: Applicable under 3-pole serial connection scheme.
*8: Expected service life based on endurance test. The service life of ACB depends on the working and environmental conditions. Refer to chapter 6

Maintenance, Inspection and
Parts Replacement
”
