Thermal Magnetic Circuit Breaker Symbol

Circuit breaker thermal magnetic 3p.

Thermal magnetic circuit breaker symbol.

Circuit breakers may also use the higher current caused by the fault to separate the contacts such as thermal expansion or a magnetic field. I had to create a thermo magnetic cb symbol. In american homes today thermal magnetic circuit breakers are the most common type. Horizontal symbol vertical symbol description hcb1 vcb1 circuit breaker 1 pole hcb11th vcb11th thermal circuit breaker hcb11thi vcb11thi current limit thermal hcb11q9 vcb11q9 magneto thermal hcb11q13 vcb11q13 magneto thermal with differential hcb11q17 vcb11q17 differential hcb11q29 vcb11q29 with current protection hcb11q33 vcb11q33 with current protection and lack of voltage.

We have thermal motor circuit protector and fused motor circuit protector symbols in our circuit breaker disconnect menu. Available in svg png jpg dxf dwg formats. The first component is an electromagnet that is sensitive to large surges in electrical currents. 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.

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. This symbol represents circuit breaker with three poles. As it turns out motor circuit protectors are. It connects three phases whenever there is an overload or short circuit in any phase the circuit breaker trips all three phases simultaneously.

These are circuit breakers which utilize two components to detect electrical faults.
