Abstract
The present disclosure relates to a circuit breaker terminal box having a leakage current blocking function, in which a current leaking from both an input side and an output side of an earth leakage circuit breaker may be limited by expanding areas of a neutral line input terminal and a neutral line output terminal on both the input side and the output side of the earth leakage circuit breaker, and thus the risk of electric shock to the human body due to the leakage current can be minimized.
Claims5
A circuit breaker terminal box, the circuit breaker terminal box comprising:
- an earth leakage circuit breaker;
- a neutral line input terminal area expansion unit that is coupled to an input side of the earth leakage circuit breaker and is in electrical contact with a neutral line input terminal on the input side of the earth leakage circuit breaker to expand an area of the neutral line input terminal on the input side of the earth leakage circuit breaker so as to limit a leakage current on the input side of the earth leakage circuit breaker;
- a neutral line output terminal area expansion unit that is coupled to an output side of an earth leakage circuit breaker and is in electrical contact with a neutral line output terminal on the output side of the earth leakage circuit breaker to expand an area of the neutral line output terminal on the output side of the earth leakage circuit breaker so as to limit a leakage current on the output side of the earth leakage circuit breaker;
- a lower housing in which internal components including the earth leakage circuit breaker, the neutral line input terminal area expansion unit, and the neutral line output terminal area expansion unit are accommodated;
- and
- an upper housing coupled to an upper portion of the lower housing and configured to protect the internal components.
