• The circuit breaker is only operated as and when required; the frequency of maintenance of ACB/BOCB/MOCB is dependent on number of short circuit operations and the switching applications
• It is cheaper and simpler alternative to enhance the life for the old installation whose service life in almost over or even surpassed
• The benefits of modern technology viz. vacuum technology can be made available with minimum installation cost; the frequency of maintenance of can be drastically reduced as VCB used in place of ACB/BOCB/MOCB
• There is no need to store large quantity of costly spares of ACB/BOCB/MOCB which may not be available because its manufacturing has become obsolete.
