Residual Current Circuit Breaker

Listing ID #4327375

From large buildings to private homes, from industries to hospitals, electricity is essential. The extensive use of electricity in our daily life has become so common that we tend to forget that careless of electricity can be hazardous. Every year, a large number of industrial & domestic fires are attributed to "electrical faults". Hasintroduced state-of-the-art RCCB, which is capable of detecting earth leakage current as soon as they appear and isolate the system.

RCCB is a current device and is independent of line voltage conditions. This means that it provides protection even when there is voltage dip or the neutral conductor is interrupted. In a healthy system the vector sum of all currents in phase and neutral is equal to zero. The device senses imbalance or residual currents in the system and disconnect supply systems.

• IEC 61008-1/IS 12640-1:2008/EN 61008-1
• Range:
  • 16, 20, 25, 32, 40 & 63.
  • Features:
    • Simple and robust operating system.
    • Rotary handle with ON/OFF indication.
    • Due termination for bus bar as well as cable connectiion.
    • Advance neutral.
    • Test button for regular inspection.
    • Positive contact indication.
    Salient Features:
    • Shapes compatible with and suitable for standard busbar connection to other devices.
    • Twin-puurpose terminal (lift/open-mouthed) above and below.
    • Busbar positioning optional line or load.
    • Free terminal space despite installed busbar.
    • Suitable for being used with standard fluorescent tube with or without electrical ballast (typically up to 20 units per phase conductor).
    • The device functions irrespective of the position of installation.
    • Type 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 be used for 3-pole connection. For this purpose use terminals 1-2, 3-4, and 5-6.
    • The 4-pole device can 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.
