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.

What is MCCB Panel board :- A distribution board (also known as panel board, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure. Normally, a main switch, and in recent boards, one or more residual-current devices (RCD) or residual 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.

Applicable Standard For MCCB Panel board :-

IEC standard 61439-1 covers low voltage switch-gear and control gear assemblies-Distribution boards intended to be operated by ordinary persons (DBO). It is important to compliance your MCCB Panel board with this standard. ITC India Can Help You!(https://itcindia.org/) ITC India one of the best MCCB Panel Board Testing Service Provider in India. ITC India Can do MCCB Panel Board Testing as per IEC 61439-1
