MCB - Miniature Circuit breaker, is having overload and
s.c. protection & used in domestic application

MCCB - Moulded case Circuit breaker, is having overload and
s.c. protection & used in Industrial application & Having
high s.c. capacity

RCCB : Residual current operated circuit breaker, is used
for protection against electric shock

ELCB : Earth leakage circuit breaker & is same as RCCB

MPCB : Motor protection circuit breaker, is used for
protection of motor, having s.c. and overload protection
more effective to protect motor

We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
