）
*2: With horizontal terminals for AR208D
– 216D
*3: For 2-pole applications, use two poles at both ends.
*4: 4-pole ACBs are not applicable to power distribution IT systems unless N-phase protection is provided.
*5: Varies depending on applicable standards. AC1000V applies to ACBs conforming to IEC60947-2 and JIS C8201-2.
*6: Varies depending on applicable standards. AC690V applies to ACBs conforming to IEC60947-2 and JIS C8201-2.
*7: Applicable to 3-pole ACBs with INST or MCR.
*8: For applicability to power distribution IT systems, consult us
*10: A special version of the breaker is available to use above 250V DC. Contact Terasaki for details.
*11: 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
”.
*12: For both vertical and horizontal terminals
*13: This manual covers draw-out type ACBs.
