Circuit breaker wiring mode and type
Circuit breaker connection with wiring in front of the board, after the wiring board, insertion, extraction ( drawer ) wiring and guide rail type five.
Circuit breaker wiring in front of the board
This is the most common use of limit, generally do not need special instructions. It is mounted on a circuit breaker in the complete sets of equipment (switchgear, power distribution cabinet ) when the mounting plate, whereby the breaker base connecting plate is directly connected with the power line and the load line, screw connection. For the common molded case circuit breaker, molded case circuit breaker such as CXM1 and DZ20L leakage circuit breaker is a typical example of.
Circuit breaker after the wiring board
Refers to the circuit breaker installed in the complete sets of equipment, the mounting plate, whereby the circuit breaker base connection plate has 6 ( end of power, load end of each 3) passes through the mounting plate bolt connected with the power line and the load line, nut fastening connection.
Insertion type wiring of circuit breaker
Refers to the complete sets of equipment installation on board, the first installation of a circuit breaker mounting bracket (plastic molding ), mount with 6 plugs, circuit breaker connecting board 6 socket ( power supply end, load end of each of the 3 ). Mounting surface with a connection plate ( insertion type wiring in front of the board ) or seat behind the bolt ( inserted after the wiring board ), mount a connected with the power line and the load line. When in use, the circuit breaker is directly inserted into the mounting seat. If the breaker is broken, just pull out the bad, for a good. Its replacement time than before the board, after the wiring board to be short, and convenient. According to the above, Yang type has one broadcast type and plate in front of the plate after insertion of type two, for customers to choose. As the plug, pull needs certain human, therefore the world plug-in product, its frame current limitation in the maximum 400A.
Circuit breaker draw-out connection
Refers to the complete sets of equipment mounting plate is first installed on a pumping installation units ( some called it the truck ) hand car connecting plate is connected with a power supply and a load ( in front of the plate type ), or the hand cart configuration connection bolt, the bolt passes through the mounting plate, in 6 bolt connected to the power source and the load ( plate type ). Circuit breaker gently placed on the mounting table top surface, and then with a rocker is inserted into the truck on the right side of the hole, for clockwise rotation, in turbine vortex rod engaging, circuit breaker handcart ( down and gradually until the mounting table ) wiring seat in close contact, it is connection; if you want to remove rocker, will make the anti-clockwise rotation. Extraction type applies to 400A above the frame current.
Circuit breaker drawer type wiring
Universal type circuit breaker is also divided in front of the board ( vertical ), board (horizontal ) wiring, the two collectively fixed; and there is a drawer type circuit breaker drawer, and also by the rocker clockwise or counterclockwise rotation.
Circuit breaker rail connection
Guide rail type installation is suitable for miniature circuit breakers, such as type HSM8 installation and wiring, guide with national standards, the circuit breaker embedded rail and wiring in front of the board. 3
