Difference between MCCB and MCB MCB is miniature circuit breaker which is used to break small currents. Like in domestic LT circuits.

The ratings usually end up to 100 A. MCCB is a Module case circuit breaker which has a rugged construction as it can break larger currents usually from (100-1000A). More Videos:- What is MCB? Advantages and Disadvantages of MCB Circuit Breaker - Types of Circuit Breaker - Circuit Breakers Types Circuit Breaker - How does a Circuit Breaker Work? MCB: • MCB stands for “Miniature Circuit Breaker”.

• Rated current under 100 amps. • Interrupting rating of under 18,000 amps. • trip characteristics may not be adjusted • Suitable for low current circuits (low energy requirement), i.e. Canon Lbp 5000 User Manual more.

• Generally, used where normal current is less than 100 Amps. MCCB: • MCBB stands for “Molded Case Circuit Breaker”.

• Rated current in the range of 10-2500 amps. • Thermal operated for overload and & Magnetic operation for instant trip in SC (Short circuit conditions) • Interrupting rating can be around 10k – 200k amps. • Suitable for high power rating and high energy i.e.

Commercial and industrial use. • Generally, used where normal current is more than 100 Amps. More Update visit my site: visit our Blog: Connect with me in my social page: Subscribe my youtube channel: Find us On Pinterest: Find us On Google+: Find us On Twitter: Find us On Linkedin.

MCB is an electromechanical device which guards an electrical circuit from an over current, that may effect from short circuit, overload or imperfect design. This is a better option to a Fuse since it doesn’t require alternate once an overload is identified. An MCB can be simply rearranged and thus gives a better operational protection and greater handiness without incurring huge operating cost. The operating principle of MCB is simple.

When someone gets an electric shock, then this circuit breaker cuts off the power at the time of 0.1 secs for protecting the personal safety and avoiding the gear from the circuit against short circuit and overload.ELCB is a security device used in electrical system with high Earth impedance to avoid shock. It notices small stray voltages on the metal fields of electrical gear, and interrupt the circuit if an unsafe voltage is detected.

The main principle of Earth leakage protectors is to stop injury to humans and nature due to electric shock. ELCB: An Earth Leakage Circuit Breaker was the first name given to what is now called a Ground Fault Circuit Interrupter (GFCI).

The original type of ELCB or GFCI was designed only to detect a current flowing in the safety 'ground' or 'earth' wire. If there is no fault anywhere in a circuit supplying single-phase alternating power to a unit such as an electrical appliance, machine or other equipment, the current flowing to the unit at any instant in the 'hot' or 'live' wire should exactly match the current flowing away from the unit in the neutral wire. Similarly, there should be no current flowing in the unit's safety 'ground' or 'earth' wire. It is a basic fact of electrical engineering design that all current flowing to an electrical appliance, machine or other equipment from the power generation station via its supply circuit's 'hot' or 'live' wire should only return to the power station via that same circuit's 'neutral' wire. So, as a result of that basic fact, if any current is flowing in the ground wire, it must be caused by a fault condition and the supply of current to the circuit needs to be stopped urgently.

Many years ago, before today's electronic RCDs or GFCIs were designed, much simpler electro-mechanical relays called Earth Leakage Circuit Breakers (ELCBs) were invented so that, if any such ground current exceeding just a few milliamps was detected, they would 'trip' - meaning 'operate' - to break the current supply to the circuits for which they were installed to protect. The original type of ELCB or GFCI did not check for any difference in current flowing in the live and neutral wires, which is another indication of a very serious fault condition - even if no current can be detected flowing in the ground wire - because the 'missing current' may actually be flowing to ground via someone's body! When RCDs were invented, most manufacturers of GFCIs adopted the same technology because it offers so much more protection to users than the original GFCI could ever give. In the US and Canada such devices are still commonly known as 'GFCIs' or 'GFIs' even though they have the additional 'residual current detector' functionality, whilst in Europe and elsewhere the more accurate name of 'Residual Current Detector' or RCD has been widely adopted for general use instead of using the name of the much simpler GFCI device.
