Thermal Magnetic Circuit Breaker Symbol

In american homes today thermal magnetic circuit breakers are the most common type.

Thermal magnetic circuit breaker symbol.

Such kind of breakers is used in three phase systems in industries. Circuit breaker thermal magnetic 3p. These are circuit breakers which utilize two components to detect electrical faults. Small circuit breakers typically have a manual control lever to switch off the load or reset a tripped breaker while larger units use solenoids to trip the mechanism and electric motors to restore.

Thermal magnetic circuit breaker definition. To do this i needed to combine the thermal symbol and the magnetic symbol but we don t have one for magnetic only cb s either. Circuit breakers symbols for use in electrical pneumatic and hydraulic schematic diagrams. It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously.

The first component is an electromagnet that is sensitive to large surges in electrical currents. Circuit breakers may also use the higher current caused by the fault to separate the contacts such as thermal expansion or a magnetic field. This symbol represents circuit breaker with three poles. We have thermal motor circuit protector and fused motor circuit protector symbols in our circuit breaker disconnect menu.

I had to create a thermo magnetic cb symbol.
