Residual Current Circuit Breakers (RCCB) / ELCBs

  • Residual Current Circuit Breaker - RCCB
  • Shape compatible with and suitable for standard busbar connection to other devices
  • Twin-purpose terminal [lift/open-mouthed] above and below
  • Busbar positioning optionally line or load
  • Free terminal space despite installed busbar
  • Contact position indicator red - green [Fi7 - 4 pole]
  • Suitable for being used with standard fluorescent tubes with or without electrical ballast [typically up to 20 units per phase conductor]
  • The device functions irrespective of the position of the installation
  • Types with 80A permissible short-circuit back-up fuse: Take into account overload protection
  • Tripping is line voltage-independent. Consequently, the RCCB is suitable for "Fault current/residual current protection" and "additional protection" within the meaning of the applicable installation rules
  • Mains connection at either side
  • The 4-pole device can also be used for the 3-pole connection. For this purpose use terminals 1-2, 3-4, and 5-6.
  • The 4-pole device can also be used for the 2-pole connection. For this purpose use terminals N-N and 5-6.
  • Pressing the test key 'T' serves the only purpose of function testing the residual current circuit breaker [RCCB]. This test does not make earthing resistance measurement [ R E ], or proper checking of the earth conductor condition redundant, which must be performed separately.
