current devices (type
SI
)
Protection
Circuit protection
EN 61009
When a Vigi iC120 device is combined with a iC120 circuit breaker, it provides the
following functions:
b
b
protection of persons against electric shock by direct contact (30 mA),
b
b
protection of persons against electric shock by indirect contact (
u
300 mA),
b
b
protection of installations against fire hazards (300 mA to 1000 mA).
Special feature of type
SI
:
They are appropriate for operating in environments with:
b
b
high risk of unwanted tripping: frequent lightning strikes, IT system, presence of
electronic ballasts, frequency converters, presence of switchgear incorporating
lighting type interference filters, computer system, etc.
b
b
blind sources:
v
v
presence of harmonics or high frequency rejections
v
v
presence of DC components: diodes, diode bridges, switch-mode power
supplies, etc.
b
b
protected against unwanted tripping caused by transient voltage surges
(lightning strike, operation of switchgear on the network, etc.)
