| 摘要 |
The present invention relates to a combining device of a surge protective device (SPD) and a molded case circuit breaker (MCCB), in which connection terminals protruding through the SPD to both sides of the SPD are made into an integrated form and inserted and fixed into each connection terminal of the MCCB, thereby improving workability preventing disconnection in advance. The combining device of an SPD and an MCCB comprises: an MCCB having R phase, S phase, T phase and N phase connection terminals; an SPD selectively combined to input and output connection terminals of the MCCB to protect the MCCB against external surge current or current; connection terminals protruding through the SPD to both sides to correspond to connection terminals of the MCCB; and a fastening device for connecting the connection terminals of the SPD and the input and output connection terminals of the MCCB. |
