China Circuit Breaker Manufacturer, Supplier, Factory

ST65LE-63series circuit breaker is a multi-function intelligent switch that integrates the functions of electricity metering,overload, short circuit, over and under voltage, leakage, over-temperature protection, remote opening and closing, timing,network communication and so on. It can be widely used in smart power management places such as commerce, agriculture,schools, hospitals, hotels, entertainment places, stations, cultural relics protection units, urban street lamp management andcontrol, and can also be widely used in energy consumption management in industrial and mining enterprises, office buildings and other places.It also can add the function  of over or down voltage protection function ,And rated current or leakage current adjustable function for RCBO

STSF2-63/100 100A 2p 4p Multifunctional RCBO is suitable for AC 50/60Hz, rated in a circuit with a voltage of 230V-400V and a rated current of 100A, when aperson is electrocuted or the power grid leaks. When the leakage, overvoltage, and undervoltage reach the set values, the residual current circuit breaker can quickly operate in a very short period of time quickly cut off the power supply. When the monitoring temperature of the residual current circuit breaker reaches the set value, the monitoring ground wire is not connected. When connected, the product emits an alarm sound to protect the safety of personnel and electrical equipment, and can avoid Prevent damage to equipment caused by overvoltage in the power grid. Has overload, short circuit, leakage, overvoltage Undervoltage and overtemperature protection functions can also be used to intermittently turn on and off electrical devices under normal circumstances Lighting circuits, especially suitable for industrial and commercial lighting distribution systems. The product has a small volume, compact structure, and better cost-effectiveness than other similar products. It has a beautiful appearance, High breaking capacity makes it a good choice for household power distribution. This product complies with GB/T 16917.1 and IEC 61009-1 standards and has obtained CE certification.
