Core features

FAZ-NA branch protectors and supplementary protectors

  • Current limiting design provides fast short-circuit interruption that reduces the let-through energy that can damage the circuit.
  • Thermal-magnetic overcurrent protection.
  • Six levels of short-circuit protection, categorized by B, C, D, K, S and Z curves.
  • Trip-free design. Breaker cannot be defeated by holding the handle in the ON position.
  • A color-coded red and green indicator provides immediate visual indication of device status (green for OFF, red for ON) and isolation function.
  • Power to the circuit breakers can be fed from the line or load side.
  • Easy installation on DIN rail. Module width of only 17.5 mm (per pole).
  • FAZ-NA branch protectors - Fulfill UL 489, CSA C22.2 No.5 and also IEC 60947-2 Standard. For use in applications for which UL 1077 or CSA C22.2 No.235 are also allowed.
  • FAZ supplementary protectors - For use in applications for which UL 1077 or CSA C22.2 No. 235 are required.
