The shutter shall be gravity operated.

FRONT DOOR :- The front door of the breaker should not be set as front. High-Voltage door during switching operations, the high-voltage door should remain closed and mechanical interlock should prevent opening of door when the switching device is in service and is switched ON. The position of the withdraw-able section, the CLOSED/OPEN switch position of the switching device, the operating cycle counter and the “spring charged” indication should be visible through pressure-resistant inspection windows in the high-voltage door. The panel front door can be closed with the breaker in isolated position. The degree of protection in the panel is IP-43 as per Indian Standard IS 3427. BUBAR: The spacious bus bar compartment is provided on the top of the cubicle. The main bus bar can carry current upto 1000A and are made of electrolytic grade copper & shall be vertically placed one after another. The bus bars should be air insulated but must be HT PVC sleeved & color coded for R-Y-B. No live parts should be accessible. All joints should be covered with monoplast compound and color coded for easy identification. The feeder connection to the busbars are preffered to be encapsulated. BREAKER: The vacuum circuit breaker is mounted on a truck and is of horizontal isolation and horizontal drawout/Vertical isolation & horizontal drawout type having a robust motorized mechanism.
