Differences between MCB and MCCB, and characteristics The first thing here is to know the meaning of the abbreviations MCB and MCCB. What does MCB and MCCB stand for? MCB stands for Miniature Circuit Breaker. MCCB stands for Molded Case Circuit Breaker Miniature Circuit Breaker (MCB) It is an electromechanical device used to protect a low load electrical circuit. It is thermally operated and used for protection against over load, heating and short circuits, in circuits requiring a small current rating (less than 100A). It is designed to replace the ancient fuse rewirable device. The Miniature circuit breaker (MCB) functions as an automatic switch OFF device which routinely turns OFF when the current flowing through it passes the threshold (maximum acceptable limit). This is achieved through the use of a bimetallic strip which protects against overload and the use of a solenoid which protects against short circuit. Application of MCB : low load domestic and in...

Interfacing infrared ranger module and object detection using GP2D120 IR sensor and PIC microcontroller Functioning of the IR Ranger Module There are several ways of Measuring range. The easiest way is by using sound waves where ultrasonic sound is fowarded, and is reflected when hit by an object and the time it takes to reflect back is measured. Sounds waves do not travel fast, and can be measured by present day equipment. However, in the case of infrared light, the time it takes to hit an obstacle and reflect back can not be measured because infrared light travels fast. An IR transmitter emits infrared light to the object in front, by passing through a condense lens. Refraction occurs once the light hits the surface of the object. Part of the refracted light falls on the receiver end which is then passed to another lens and processed by an array of photo-transistors. Hence, the position in which the light falls can be used to calculate the distance of an obstacle from the tr...

Conveyor Belt project design for an Industrial sorting and counting machine A conveyor belt is a machine or device used to convey or carry materials or items. It is mostly used in industries to carry products to be manufactured or already manufactured products. Used since the 19th century where Thomas Robins began a series of invention which led to its development. It was greatly used for transportation of agricultural products, carrying coal over long distances and other mining products. It generally consists of two end pulleys, with a continuous loop of material which rotates round them. An electric motor coupled to one or both of the pulley(s) provides a driving force to rotate the belt. The rotation of the belt is due to friction between the rotating pulley and the belt. A flat surface or carcass may be used to provide support to the belt. Below is a view of a mini conveyor belt design for an industrial sorting machine. Mini conveyor belt To watch video of the conveyo...
