Circuit breaker vertical installation or horizontal installation, the circuit breaker panel nameplate or logo as a parameter, the circuit breaker above the terminal as the power into the terminal, also known as the power supply terminal, the circuit breaker below the terminal As the load connector, also known as the load side, this connection, known as the line up; the other on the line into the line breaker as the load side, the load side as the power side to use the wiring, said the next line. Breaker connection is usually the way up line, but often because of the occasion of the installation, the way into the line under the circuit breaker requirements. For example: the power supply is located below the power distribution cabinet, the power supply line to the load side of the circuit breaker more convenient; there are cabinet up and down with two or two rows of circuit breakers, power into the line from the middle part of the introduction of the upper and lower Two or two rows of circuit breakers, respectively, into the line and the line up the wiring. There is also a special case, no matter what kind of measures are taken to avoid the way into the line, in the construction of electrical more classic form of the Union. In practice, three locks and two keys are commonly used to ensure the reliability of the chain. For example, the HSW1 series intelligent universal circuit breaker has the function of locking all three circuit breakers with the same lock Buckle parts, three circuit breakers can only be equipped with two the same key, when the key is inserted and unlocked, the circuit breaker mechanism to operate, so that the circuit breaker normally closed. QF3 is not equipped with a key during normal operation, and circuit breaker QF3 is in the off position. When any one of the two power supplies, such as QF2, fails to supply the QF2 key to QF3, QF2 turns off and QF3 closes. All loads are supplied from the same power supply via QF1 and QF3, and QF3 is on line mode . When QF1 can not supply power, all the loads are supplied by the same power source through QF2 and QF3. In this case, QF3 is the down line mode. Therefore, for the QF3 circuit breaker, no matter what the connection mode, There is always one way up the line, one line into the line, so speaking of such occasions can not be avoided using the next line.
