Fuses and Electrical Protection Symbols. Fuses are devices containing a small piece of special wire that melts when the intensity of the current flowing through it for a certain period of time exceeds a set value, thus protecting the rest of the electrical circuit overloads.
(general symbol) An amplifier circuit with one input. Really it is a block diagram symbol because it represents a circuit rather than just one component. Aerial (Antenna) A device which is designed to receive or transmit radio signals. It is also known as an antenna.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume ...
A circuit diagram or wiring diagram uses symbols to represent parts of a circuit. Electrical and electronic circuits can be complicated. Making a drawing of the connections to all the component parts in the circuit's load makes it easier to understand how circuit components are connected.
the symbol. The distiguishes like symbols from one another. The following examples are typical: 1200 A Identiﬁes the drawout circuit breaker represented by the symbol as a 1200 ampere circuit breaker. 225 A/3P Indicates the ﬁxed circuit breaker represented by the symbol as a 225 ampere, 3-pole breaker.
Electrical IEC symbols: Circuit Breaker Thermal and Magnetic 1P-Q347. Stencil: Electrical (IEC) Isolators, Disconnectors, Fuses, Contactors. DXF, DWG and Visio formats available.
We know that both fuse and circuit breaker having the same rated current (say 30A) will not trip when more than 30A (say 32) is flowing through them. But there is a big difference between fuse and circuit breaker i.e. both circuit breaker and fuse with same rated current has different properties.
