DACF15-30-275
Part Number: 821310213
  • Type 2 (or 3) AC surge protector
  • Interne Disconnection device
  • Low caliber of the internal connector = systematic coordination with upstream circuit breaker
  • In : 5 kA
  • Imax : 15 kA
  • Pluggable module for each phase
  • Remote signaling option
  • EN 61643-11, IEC 61643-11, UL1449 ed.4 compliance

The special feature of this series is the integrated and monitored back-up fuse, which makes the use of an additional external back-up fuse unnecessary. Type 2 (or 3) DACF15 SPDs are used mainly for primary surge protection of single and 3-phase AC networks at the main switchboard. In addition to their thermal disconnector, the range is equipped with a internal fuse against short-circuit currents, which avoidsthe use of a external fuse or circuit-breaker as requested by standard. The operation of one of the both disconnectors will activate the indicator and the remote signalling (option). This compact solution simplifies the implementation and minimum space. The DACF15 surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase.
