Presenting Power Safety of MCCB Panel Board
Objectives of MCCB Panel :-MCCB panel boards have been designed for easy handling and quick, simple installation for the electrical contractor. Compact MCCB design ensures maximum cabling area within the enclosures. Removable top & bottom gland plates are provided for ease of installation and cabling. The removal of these also allows for fitting of additional items such as top and bottom extension boxes, plinths and metering panels.
Objectives of MCCB Panel
What is MCCB Panel board :-A distribution board (also known as panel board, breaker panel, or electric panel) is a component of anelectricity supply systemthat divides an electrical power feed into subsidiarycircuits, while providing a protectivefuseorcircuit breakerfor each circuit in a commonenclosure. Normally, a mainswitch, and in recent boards, one or moreresidual-current devices(RCD) orresidual current breakers with overcurrent protection(RCBO), are also incorporated.
What Is Function of MCCB in electrical Circuit :-Molded Case Circuit Breaker (MCCB) is a circuit breaker and trip device assembled in a mould case. Also it can automatically cut off electric power in case of overload and short circuit. It is meant for higher rated current and is commonly used in Industrial applications.
