- Note sulla selezione
- Breaking capacity matching: Select V/S/H/N/L classes based on system short-circuit current calculation
- Protection function selection: Basic LS/I meets most needs; choose LSIG for earth fault protection
- Mounting type: Fixed for standard switchgear, draw-out for easy maintenance and replacement
- Accessory configuration: Select auxiliary contacts, alarm contacts, motor operators, ecc., according to control requirements
- Voltage compatibility: T6V suitable for systems up to 690V; use dedicated 1000V series (per esempio., T6L) for higher voltages
