It's called knockoff because if you want the breaker to disconnect the power, you have to knock it off the bus bar. 121. AgelosSp. That's European, if we want to turn off the circuit we have to fumble with a screwdriver, or for the lucky ones among us, stick yer tongue in an outlet and hope the RCD trips.

Short-time delay refers to the length of time the breaker will allow stronger current surges before the breaker trips. The time may or may not be affected by the strength of the current, depending upon the I² T setting. On the curve, the short-time delay is represented by either a horizontal line or a slope to the right of the short-time … WebLow voltage circuit breakers with a thermal-magnetic trip device allow for the discrimination between an overload from a fault. The thermal element acts as protection from overloading while the magnetic element is for protection from faults. This allows slow operation on overload and fast on fault.
