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 installation
Types with 80A permissible short-circuit back-up fuse: Take into account overload protection
Tripping is line voltage-indepedent. 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 3-pole connection. For this purpose use terminals 1-2, 3-4 and 5-6.
The 4-pole device can also be used for 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 resistence measurement [ R E ], or proper checking of the earth conductor condition redundant, which must be performed separately.
