Mcb mini circuit breaker seiko manufacturing solid protection for your electricity safety escort.From the modeling design to the process of material selection after repeated grinding.Leakage protection system partition structure design, anti-interference, reliable operation of the circuit board, special moisture-proof technology, effective protection under humid environment, special protective cover, heat resistance, good heat dissipation.
Mcb mini circuit breaker the environmental temperature adaptability is strong to meet the application needs of various occasions, and can run reliably under harsh environment.Seiko manufacturing to ensure the safety of household electricity strictly control each manufacturing detail.
In order to ensure the safety of the circuit breaker, the control circuit often adopts a variety of blocking measures. When the conditions are not met, the operation of the circuit breaker is prohibited. There are generally three common latching circuits:
(1) When the operating system of the circuit breaker is abnormal, the opening and closing circuits are blocked. When the hydraulic pressure of the hydraulic mechanism and the air pressure of the air operating mechanism are too high or too low, the spring of the spring operating mechanism is not stored, the SF6 pressure of the SF6 Mcb Mini Circuit Breaker is low, etc., these will be connected in series in the tripping and closing circuits. The normally closed contact is open, and the circuit breaker is not allowed to open or close.
(2) Where there are different power sources that need to be paralleled, the circuit breaker control circuit should be added with a synchronous lockout circuit.
(3) In order to meet the needs of preventing misoperation, an anti-misoperation locking circuit should be added to the operating circuit of the circuit breaker, and the control circuit should be disconnected when the operating conditions are not available.
