Delixi leakage maintainer is mainly when the electrical equipment leakage problem to provide maintenance of the device, when the installation of leakage maintainer, should be other devices overcurrent maintenance device. When the fuse is used for short-circuit maintenance, the selection of its standard should be compatible with the on-off of the leakage maintainer. Leakage circuit breakers, which combine leakage maintenance devices with power switches (active air circuit breakers), are now widely used, and this new type of power switch has the performance of short-circuit maintenance, overload maintenance, leakage maintenance, and undervoltage maintenance. The wiring is simplified, the size of the electrical box is reduced and it is easy to manage.

A brief introduction to Delixi leakage circuit breaker

The significance of the nameplate model of Delixi leakage circuit breaker is as follows: attention should be paid to the use, because the leakage circuit breaker has multiple protection functions, when the occurrence of tripping, the fault factors should be specifically distinguished: when the leakage circuit breaker is broken due to short circuit, the cover must be opened to see whether the contact is seriously burned or pitted; When tripping due to line overload, it cannot be closed from the beginning immediately.

Because the circuit breaker is equipped with a thermal relay as an overload maintenance, when the additional current is presented, the bimetal sheet bends to separate the contacts, and it is necessary to wait for the bimetal sheet to cool down and recover to its original state before the contacts can be closed from the beginning. When tripping due to leakage problems, it is necessary to find out the factors and eliminate the faults before closing from the beginning, and it is forbidden to forcibly close. When the leakage circuit breaker breaks and trips, the L-like handle is in the middle position, and when it is closed from the beginning, it is necessary to pull the operating handle down (breaking direction) first, so that the operating mechanism is re-buckled, and then close upward.

The leakage circuit breaker can be used for switching appliances with large capacity (greater than 4.5kw) power line and infrequent operation. Plastic shell circuit breakers are divided into air circuit breakers and leakage circuit breakers, and there are generally three types: with short circuit and overload maintenance functions. It has the function of leakage maintenance. It has the functions of short circuit, overload and leakage maintenance. Leakage refers to the single-phase leakage of the line after the switch to the switch, and the additional leakage current switch will jump, and then play a maintenance role.
