RESIDUAL CURRENT CIRCUIT BREAKERS

POWERTEC’s F17 RCCB is a current operated device and is independent of line voltage conditions. They provide protection even when there is a voltage dip or the neutral conductor is interrupted. The device senses imbalance or residual currents in the system and disconnects the supply system.

• 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 (F17-2 pole/4 pole)
• Suitable for being used with standard flourescent tubes with or without electrical ballast (typically up to 20 units per phase conductor)
• Mains connection at either side. The device functions irrespective of the position of installation
• Types with 80 A permissable 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.
• 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 resistance measurement (RE), or proper checking of the earth conductor condition redundant, which must be performed separately.
