N O T E
• Electric fuses can be used instead of magnetic Circuit Breakers (CB). In that case, select fuses with similar rated values as the CB.
• The Earth Leakage Breaker (ELB) mentioned on this Technical Catalogue is also commonly known as Residual Current Device (RCD)
or Residual Current Circuit Breaker (RCCB).
• The Circuit Breakers (CB) are also known as Thermal-Magnetic Circuit Breakers or just Magnetic Circuit Breakers (MCB).
