Abstract
The present disclosure relates to a three-phase terminal block having a leakage current limiting function, in which a leakage current may be limited by expanding an area of a neutral line of a three-phase four-wire line connected to the terminal block, and thus the risk of electric shock to the human body due to the leakage current may be minimized.
Claims3
A three-phase terminal block having a leakage current limiting function, the terminal block comprising:
- a first-phase conductor electrode having both ends to which a primary-side first-phase voltage line (R line) and a secondary-side first-phase voltage line (R line) of a three-phase four-wire line are electrically connected;
- a second-phase conductor electrode having both ends to which a primary-side second-phase voltage line (S line) and a secondary-side second-phase voltage line (S line) of the three-phase four-wire line are electrically connected;
- a third-phase conductor electrode having both ends to which a primary-side third-phase voltage line (T line) and a secondary-side third-phase voltage line (T line) of the three-phase four-wire line are electrically connected;
- and
- a neutral line area expansion unit that has both ends to which a primary-side neutral line (N line) and a secondary-side neutral line (N line) of the three-phase four wire line are electrically connected and limits leakage current by expanding the areas of the neutral lines.
