Magnetic Circuit Breaker Symbol

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

Magnetic circuit breaker symbol.

Circuit breaker with magnetic overload device 3p. All symbols electrical installations switchgear and protective devices ansi protective devices circuit breakers. The first component is an electromagnet that is sensitive to large surges in electrical currents. Circuit breaker with thermal overload device 3p form 1.

Electrical surges can cause short. Thermal magnetic circuit breaker definition. Such kind of breakers is used in three phase systems in industries. Protection against overload and short circuits using thermal overload relays electro magnetic relays circuit breakers with releases fuses etc.

This symbol represents circuit breaker with three poles. These are circuit breakers which utilize two components to detect electrical faults. 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.

Power circuits have to carry heavy power and therefore they consist of heavy conductors along with contactors used for switching the power on and off. 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.
