NBSe NBSK1-125 4P 80A circuit breaker type ac disconnector switches isolation
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.

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.
FAQ:
Q1: What's your product Range?
A.
-Shell Unti-fire. nylon pa66 or not unti-fire.
-Parts, Copper or iron
-Point Sliver point or Copper point
Q2: Are you a manufacturer?
A. Yes, we are only produce the circuit breaker over 20 years from 1999.
Q3: Do you have stock products to sell?
A. No,we work on OEM orders, The means, material, quantity,packing solution,etc will depend on your requests.obviously, your logo can be printed on the products.
