Thermal Breaker Symbol

Circuit breakers symbols for use in electrical pneumatic and hydraulic schematic diagrams.

Thermal breaker symbol. In american homes today thermal magnetic circuit breakers are the most common type. 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. The first component is an electromagnet that is sensitive to large surges in electrical currents. Fuses and electrical protection symbols.

It operates on the temperature rather than the current unless the current is sufficient to increase the temperature above the threshold point. Available in svg png jpg dxf dwg formats. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume. Thermal magnetic circuit breaker definition.

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. A thermal fuse is a temperature sensitive switch.
