How large a leakage protector is used for the construction elevator
If it is 33KW, direct start, single cage, 160A, leakage action current 50ma-75ma, movement time 0.1 s, electrical machine leakage protector. The best.
A leakage switch with a rated current of 100-160a. The rated action current of the second class is 50-75hm. The rated action current is 30-45hm. The action time is less than or equal to 0.1 s. Comply with safety specification according to this construction.
The leakage current is less than 30 milliamps The short circuit current is typically 1.2 to 1.5 times the rated current If the motor is rated at 10, it is usually used with a 125-15 leakage protector
