Switch Gear

the power instability in developing countries along with the inefficient rationalized power distribution creates a need for the alternative source of power, to back up the utility supply. This further necessitates the automation, in the distribution system as the rate of power outage & low voltage output becomes predominantly high. Most of the residential & commercial processes are dependent on power supply & if the process of changeover is manual, this will not only create the hindrance in important activities but it may also damage the device or machine from human error during the changeover.
havells accl is a fully automatic high precision microcontroller based device having current limiting function providing on both generator supply & mains supply and is ideally suited for proper/efficient utilization of standby generator used in multi-storied apartments, commercial complexes, etc.

The flow of current through electrical facilities always involves risks. Poorly insulated equipment, faulty wires and incorrect use of an electrical device cause currents to flow through the wrong path (i.e., through the insulation) to the earth. This current is called 'Leakage Current'.

Earth Leakage is an electrical hazard and is responsible for electrical shocks and fire risk. Earth Leakage and its associated hazard can be prevented by residual current circuit breaker (RCCB), also popularly known as Earth Leakage Circuit Breaker (ELCB).
