Residual Current Device Mini Circuit Breaker 2 Pole RCCB 16A 25A 40A 63A
KRIPAL has the design patent for these items
A residual-current device (RCD), or residual-current
circuit breaker (RCCB) is an electrical
wiring device that disconnects a circuit 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 through the body of
a person who is grounded and accidentally touching the energized
part of the circuit. A lethal shock can result from these
conditions. RCCBs are designed to disconnect quickly enough to
prevent injury caused by such shocks. They are not intended to
provide protection against overcurrent (overload) or
all short-circuit conditions.

Instantaneous tripping current:
International Standard--- IEC 60898-1 and European
Standard EN 60898-1 define the rated
current In of a circuit breaker for low voltage
distribution applications as the maximum current that the breaker
is designed to carry continuously (at an ambient air temperature of
30 °C). The commonly-available preferred values for the rated
current are 6 A, 10 A, 13 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63
A, 80 A, 100 A,[5] and 125 A (Renard series, slightly modified
to include current limit of British BS 1363 sockets). The
circuit breaker is labeled with the rated current in amperes,
but without the unit symbol "A". Instead, the ampere figure is
preceded by a letter "B", "C" or "D", which indicates
the instantaneous tripping current — that is, the minimum
value of current that causes the circuit breaker to trip without
intentional time delay (i.e., in less than 100 ms), expressed in
terms of In:
Type | Instantaneous tripping current |
B | above 3 In up to and including 5 In |
C | above 5 In up to and including 10 In |
D | above 10 In up to and including 20 In |
