I²t INâresults in an inverse-time delay characteristic that most closely Long-time delay causes the breaker to wait a certain amount of time to allow temporary inrush currents, such as starting a motor, to flow without tripping. Joined: 7 Apr 2006 Messages: 38 Thanks Received: 0 Location: Sheffield Country: I've just had a long conversation with a NICEIC inspector regarding which RCD out of a 30mA and a 100mA would trip with a fault current first? Full disclaimer here. T3 â T2 is overloading period of these two contacts (moving and fixed contact). Background. the cost of 5 adult tickets and 8 childrens tickets is $88. Tripping classes of the thermal overload relays Standard tripping classes are 10 A, 10, 20, 30. IEC 60898-1 defines the Conventional non-tripping current and Conventional tripping current of a circuit breaker is 1.13In and 1.45In. 3 times the population (3p) = the population (p) times e^(kt) where k is a growth rate and t is time. 3 = e^(kt) (the p's can be divided from both sides), ln(3) = kt (take the natural log of both sides). Here in the graph, X axis represents time in milli seconds and y axis represents distance in milli meter. Tripping time Seconds Minutes I 1 = 1.05 x l n 2 = 1.2 x l n J R = 20 °C (K, Z) I 1 = 1.13 x l n I 2 = 1.45 x l n J R = 30 °C (B, C, D) Tripping curve from cold state But we should remember, that, one circuit breaker remains at its closed position for maximum period of its life span. After time T 3 the moving contact bounce back little bit and then again comes to its fixed closed position, after time T 4. As the contact gap reduces, arcing may start before contacts are closed finally. The nominal pickup point where a circuit breaker trip unit detects an overload is at 1.075 times the selected ampere rating. I understand that when carrying out RCD testing an RCD should trip within 300ms at 1x and 40ms at 5x but is it common that on occasions for the RCD to trip quicker at 1x than 5x.
