Q:How to look at the circuit breaker capacity is how much?
The rated breaking current of the circuit breaker is three times the root number of the product of the rated voltage, that is, the blocking capacity.
Q:Does the isolator and circuit breaker able to switch to each other?
Yes, it just provides a clear breakpoint, and now there are visible breakpoints that have obvious breakpoints.
Q:Circuit problem! Hurry Miniature Circuit Breaker!
First determine whether the circuit breaker inlet and outlet connections are loose, because the circuit breaker trip is bimetallic due to overheating caused,
Q:Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
the emission junction and the collector junction between the almost no current, the equivalent of 5.0V and R10 disconnected
Q:How is the circuit breaker different from the air circuit breaker?
Transformer, line capacitance current and other small load), knife fuse switch is a switch and fuse combination of electrical appliances,
Q:Is the isolator switchable with a circuit breaker?
Circuit breaker: with overcurrent, short circuit automatic trip function, with degaussing arc extinguishing device, can be used to connect, cut off the high current;
Q:What is the length of time that the circuit breaker can delay?
do not know what kind of circuit breaker you said. Long delay function in general is a trip time and overload current into inverse time relationship
Q:What type of switch circuit breaker has undervoltage protection
For example: Model DZ10-100 / 330 circuit breaker with over voltage, undervoltage protection function, from its model in the symbol / behind the second 3
Q:Home no electricity corridor switch the total switch circuit burned how the matter
here are two general reasons, one is the switch quality is not good, the second is the existence of the installation quality defects
Q:Do you have a circuit breaker in the circuit?
that your electrical equipment is a three-phase motor, if the line has a phase failure such as ground fault, etc.
