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. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume. It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously. Motor circuit protectors motor circuit protectors provide short circuit protection for individual motor loads and are available for a wide range of motor sizes and installation types.

Such kind of breakers is used in three phase systems in industries. Available in svg png jpg dxf dwg formats. Protection against electrical faults such as short circuits line to ground faults and line to line faults. Circuit breakers symbols for use in electrical pneumatic and hydraulic schematic diagrams.
