Dc Circuit Breaker Symbol

Such kind of breakers is used in three phase systems in industries.

Dc circuit breaker symbol. The main difference between direct current and alternating current. 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. 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 protection. Fuse a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.

Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume. 72 dc circuit breaker 74 alarm relay 75 position changing mechanism 76 dc overcurrent relay 78 phase angle measuring or out of step relay 79 ac reclosing relay 81 frequency relay 83 automatic selective control or transfer relay 84 operating mechanism 85 carrier or pilot wire receiver relay 86 lockout relay. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Fuses and electrical protection symbols.

Dc circuit breaker like their name suggests is used for the protection of electrical devices that operate with direct current.
