The document provides an overview of various electrical components used in circuits and machines, including fuses, miniature circuit breakers (MCBs), moulded case circuit breakers (MCCBs), motor protection circuit breakers (MPCBs), relays, contactors, push buttons, connectors, cables, terminals, and busbars. It describes their basic functions such as overcurrent protection, switching circuits, connecting wires, and carrying large currents within electrical equipment.

3. FUSE A safety device that protects an electric circuit from becoming overloaded.

5. MINIATURE CIRCUIT BREAKER (MCB) An automatic switch that stops the flow of electric current in a suddenly overloaded or otherwise abnormally stressed electric circuit

9. Type B devices are generally suitable for domestic applications. They may also be used in light commercial applications where switching surges are low or non-existent. Type C devices are the normal choice for commercial and industrial applications where fluorescent lighting, motors etc. are in use. Type D devices have more limited applications, normally in industrial use where high inrush currents may be expected. Examples include large battery charging systems, winding motors, transformers, X-ray machines and some types of discharge lighting. Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device). Type D devices are designed to trip at 10-20 times In (100-200A for a 10A device). MCB TRIPPING
