4P 250-400A 1000V DC MCCB

The rated working voltage of this model is 1000V, and the rated current is 400A, which can withstand large power load, effectively prevent electrical accidents caused by overload, short circuit and other faults, and ensure the safety of equipment and personnel. CE certification marks its compliance with European safety, health and environmental standards, and has good universality and recognition in the international market. The rated impulse voltage capability of 12kV, makes it excellent in dealing with the instantaneous voltage impulse in the power grid, which greatly enhances the stability and reliability of the system.

High voltage and high current carrying capacity: It can meet the power distribution needs in high voltage and high current environments, and can stably operate in industrial production and other scenarios with demanding power requirements, such as power equipment power supply lines in large factories.
Reliable protection performance: Sensitive detection of short circuit and overload fault and fast cutting ability, through the precise electromagnetic trip and thermal trip mechanism, to ensure rapid action when the fault occurs, effectively protect downstream equipment.
CE certification: Following the internationally recognized safety standards, product quality and safety have been strictly tested, and can be used with confidence in Europe and other regions that recognize CE standards, reducing 4P 250-400A 1000V DC MCCB quality concerns.
Optional alarms: To meet the needs of different customers for fault alarms, additional alarm options are provided. When the circuit breaker is tripped, the alarm can send a sound signal in time, which is convenient for the operator to quickly locate the fault point in the complex electrical environment, and take timely repair measures to reduce downtime and potential losses.

Shell design: The use of high strength plastic shell, with good insulation performance and mechanical strength, can effectively prevent electric shock accidents, and resist a certain degree of external impact and environmental erosion, to ensure the safe and stable operation of internal electrical components.
Internal structure: The internal contact system uses high quality conductive materials, small contact resistance, can carry large current and ensure good conductivity, reduce heating and energy loss. With advanced design, the arc extinguishing chamber can quickly extinguish the arc generated when the circuit is cut off, effectively prevent the secondary accident caused by arc reignition, and improve the breaking capacity and service life of the circuit breaker. At the same time, the tripping mechanism is accurate and reliable, the action is fast, and the precise response can be made according to the preset current threshold, to ensure the timeliness and accuracy of the protection action.
