Main Breaker – Residual Current Circuit Breaker iID (RCCB)
LVLØ built in RCCB from Schneider-Electric, Acti 9 range - provides absolute people protection (30mA
sensitivity for protection against direct contact), protection of equipment against electrocution (in
accordance with installation standard IEC 60364 and national
standards), protection from risk of fire due to current leakage into
building electrical installations and improved continuity of service.
Acti 9 covers all applications, especially in polluted environments and
networks.
Acti 9 exclusivities:
VISI-SAFE
–
Guaranteed
safe
intervention on site, contact position
indication with the green strip,
insulation voltage 500 V, pollution
degree level 3 (conductive pollution, dust, harsh environment)
VISI-TRIP – Indicator makes it easy to spot a tripped circuit breaker to
minimize downtime
Front face class 2 - Continuous safety for operators and non-qualified personnel
It automatically disconnects whenever it detects that the electric current is not balanced between the
energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage
(for ex. through the grounded body of a person). RCCB is designed to disconnect quickly enough to prevent
injury caused by shocks. They are not providing protection against overcurrent (overload) or all short-circuit
conditions. RCCB is compliant with standard IEC EN 61008-1, certified by national official authorities and is
suitable for isolation in accordance with industrial standard IEC/EN 60947-2.
This device enables the mechanical parts of the RCCB to be verified by pressing the button marked „T“.
NOTE:
Do not use test button to switch OFF RCCB.
A test for the effectiveness of the RCCB in the
protected installation should be carried out,
periodically, based on maintenance standards.
To test the operation of the RCCB after installation:
o
RCCB must be in ON position and
energized,
o
press the „T“ button on the front of the
device,
o
The RCCB should trip immediately.
Failure to do so indicates either no supply to the RCCB or a faulty device.
Failure to follow these instructions can result in equipment damage!
