Circuit breaker always trips the circuit but when there is an open contact of the breaker, it cannot be physically seen from outside of the breaker and that is why it is considered as the “not to touch” area of the electrical circuit. Thus, the isolators are created for the safety so that, one can see the condition of the section of the circuit before touching it. The isolator is a switch which isolates the part of the circuit system when it is required. Electrical isolators are the separate part of the system that is created for the safe maintenance. Isolators are generally used at the end of the breaker to repair or to replace.
Isolators are generally used in power system while on the other hand, MCB is the circuit breaker. Isolators are manually-operated device, and on the contrary, the circuit breaker is the automatically-operated device. Isolators cut the portion of the substance when a fault occurs. The other devices like MCB and RCCB operate without any interruption. The circuit breaker is the device of an Automatic circuit breaker or Miniature circuit breaker which trips the entire system and if any fault occurs, MCB is to protect the wires from the damage. Whereas, on the other hand, residual current device protects the life-threatening problems. RCCB detects the leakage current and protects from the electric shock.
So, this is MCB, Isolators and RCCB and the difference between them.

Q5. how's the delivery time ?
A. usually it will take about 30 days for 30000pcs
Q6. tell me the standard of package?
A. Normally are cartons, color box or white box
Q7. what kind of material of circuit breaker?
A. we have two types, one copper coil with silver point and the other is brass coil with copper point. It depends on your requirement. In fact, those two have no difference if normal work well. Only except the electrical life. Copper and silver is better and also higer price.
