Technical info

Rated residual action current 0.03 A / 0.1 A / 0.3 A • IEC/EN 61009-1

• Fork and pin busbar connection (top/bottom)
• With leakage fault indication
• Mounting on TH DIN35 rail
• Connection capacity 1–25 mm²

RCB residual current circuit breaker is intended for AC 50/60 Hz
circuits with a rated voltage of 230 V (2-pole version) or 400 V
(4-pole version) and a rated current up to40 A lines. When a person
is electrocuted or the leakage current of the power grid exceeds
the specified value, the circuit breaker can quickly cut off the faulty
power supply in a very short time, protecting the safety of people
and electrical equipment. It can also be used for overload and short
circuit protection of the line, and for infrequent on-off operation under
normal circumstances.

Circuit breakers are suitable for various occasions such as industrial,
commercial, high-rise, and residential use.
