Selection Reminders
- ABB AF uses electronic wide-voltage coil, different principle from Siemens traditional electromagnetic coil, surge suppression solution differs;
- Schneider TeSys Giga overall size and mounting pitch differ from legacy LC1F and Siemens S10, cabinet space must be rechecked for retrofit;
- For direct replacement of old LC1F265, OEM recommendation is LC1G265KUEN;
- If you prefer built-in 2NO+2NC without extra auxiliary block, ABB AF265-30-22-12 is preferred.
