STRO7-40 RCBO, full name is Residual Current Circuit Breaker with Overcurrent Protection. It is an electrical safety device that integrates overload protection, short-circuit protection and leakage protection, and is widely used in electrical systems in residential, commercial and industrial areas to ensure personal safety and safe operation of equipment.STRO7-40 RCBO is an important electrical safety device with overload, short circuit and leakage protection. By understanding its working principle, characteristics, application scenarios, and selection and installation methods, you can better use and maintain STRO7-40 RCBO to ensure the safe operation of electrical systems.

STSF2-100 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.

Plug in Type RCBO 1P+N, i.e. Plug in Type Residual Current Circuit Breaker with Overload Protection (Residual Current Circuit Breaker with Overload Protection), 1P+N indicates that the number of its poles is unipolar plus zero line. It not only provides overload and short-circuit protection, but also has the function of leakage protection, which can detect and cut off the leakage current in the ground line, thus effectively guaranteeing the normal operation of electrical equipment and personal safety.

1P+N Electronic Type RCBOis a special type of circuit breaker which utilizes the electromagnetic principle to detect and cut off the residual current (leakage current) in the circuit, thus preventing electrical fires and personal electric shock accidents. At the same time, it also has an overcurrent protection function, which can automatically cut off the power supply when the circuit is overloaded or short-circuited to protect the safety of the circuit and equipment.

SONTUOEC is one of the Chinese suppliers/manufacturers specializing in the production of various small electrical appliances STRO-40L is mainly used in AC 50Hz(60Hz), rated voltage 110/220V, 120/240V, rated current 6A to 40A low voltage terminal distribution system. RCBO is equal with MCB+RCD function; It is used for electric shock protection and human indirect contact protection, electric equipment protection when human body touching electricity or electric network leak current exceeds stipulated value, and over load and short circuit protection ; It can also be a non-frequency operator in the circuit, wildly used in the residential and commercial district. It complies with standard of IEC61009-1.

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.
