4.Dimensions and installation sizes
Strong adaptability to environment and reliable operation in harsh environment
-30℃~70℃ ambient temperature range, to meet the needs of various applications
Widened handle
The curve of handle is in line with human's habit, improve the operating comfort
High current does not burn out
Built in a certain amount of magnetic, holding relay, by large current does not burn out
Increase the interface
High quality interface terminal, effectively prevent fracture, prevent leakage of electricity
Thermosetting shell
With thermosetting resin as the main component, through the process of cross-linking, the formed product can withstand high temperature and cold
Suitable for power distribution box
Suitable for large factories
Circuit breaker and leakage protection choose
1.The main switch of the household distribution box is usually a 32A-63A mini circuit breaker or leakage protection circuit breaker which can disconnect the phase line and neutral line at the same time 2.10A-16A miniature circuit breaker is generally selected for lighting circuit 3.Socket circuit generally selects 16A-20A leakage protection circuit breaker
Switch current is selected according to equipment power
1.Calculation formula = power/voltage *3 (impact current) 2.For example: 3000W equipment 380V voltage select circuit breaker, 3000W*3 (impulse current) /380V≈ 23.68A ≈25A, we choose 25A circuit breaker or leakage circuit breaker
How to choose the type C and type D electromagnetic trip
The long delay action range of type C is 5in-10in; The long delay action range of type D is 10in-12in.(In is the rated current of the switch) Type C is used in light load areas such as distribution control and lighting.Type D can be used in heavy load starting places, such as motor starting, can avoid the equipment after starting the instantaneous current is too large to cause unnecessary overload switch trip.
Can't shut down
1.Whether the load port is short circuited 2.Operating mechanism failure 3.The rated current of the circuit breaker does not match the load current
High temperature
1.The wiring screw is loose without tightening the wire 2.The chosen wire section area is too small, the wire is too thin
Not disconnected in short circuit
1.The selected circuit breaker does not match the working conditions of the load
No electricity
1.Too little lead head stripping 2.The wiring screw is loose without tightening the wire
