Electronic Tripping Type Residual Current Circuit Breaker with Overload Protection Rated Current 6A To 40A Electrical Safety Device

Product Description:

The STRO-40L Series RCBO Circuit Breaker is a reliable and efficient Residual-Current-Circuit-Breaker-with-Overload-Protection designed to provide superior electrical safety and protection in residential, commercial, and industrial applications. This high-quality device combines the functions of a circuit breaker and a residual current device (RCD) to ensure comprehensive protection against overloads, short circuits, and earth leakage currents, which can pose serious risks to both people and equipment.

With a rated current range of 6 to 40 amperes, the STRO-40L Series offers versatile options to meet various electrical load requirements. This range makes it suitable for protecting circuits in a wide array of installations, from small lighting and socket circuits to moderately demanding electrical systems. The precise current rating selection ensures optimal protection and minimizes the risk of nuisance tripping, thereby maintaining system reliability and safety.

The STRO-40L Series complies fully with the IEC/EN 61009-1 standard, which guarantees that it meets international benchmarks for performance, safety, and durability. This compliance reassures installers and end-users that the device has undergone rigorous testing for residual current detection and overload protection, ensuring it will perform effectively under fault conditions. This adherence to standards also facilitates easier certification and approval processes in various regions and markets.

Physically, the STRO-40L Series RCBO features a compact design with an 18mm width, making it an ideal choice for panel boards and distribution boxes where space efficiency is critical. Its slim profile allows for high-density installation without compromising accessibility or ease of wiring. The device is designed as a 1P+N (single pole plus neutral) configuration, providing complete disconnection of both live and neutral conductors in the event of a fault, which enhances safety during maintenance and fault clearance.

The RCBO's exterior is finished in a clean, white color, which not only contributes to a neat and professional appearance in electrical panels but also aids in easy identification and integration with other electrical components. The robust housing protects the internal mechanism from dust, moisture, and mechanical impacts, ensuring long-term reliability and consistent performance in demanding environments.

One of the key advantages of the STRO-40L Series is its Residual-Current-Circuit-Breaker-with-Overload-Protection functionality. This dual protection capability means that the device can detect earth leakage currents that could cause electric shocks or fire hazards, while simultaneously protecting circuits from damage due to overload or short circuits. This integrated approach reduces the need for separate devices, saving installation time, space, and cost.

Additionally, the STRO-40L Series is designed for ease of installation and maintenance. It features user-friendly terminals and clear labeling, facilitating quick wiring and inspection. The toggle switch provides intuitive operation for manual switching and testing, allowing users to verify the device’s functionality periodically to ensure ongoing protection.

In summary, the STRO-40L Series Residual-Current-Circuit-Breaker-with-Overload-Protection offers a robust, compact, and standards-compliant solution for electrical safety. Its rated current range of 6-40A, compliance with IEC/EN 61009-1, compact 18mm width, 1P+N configuration, and white color housing make it an excellent choice for a broad spectrum of applications. By integrating overload protection with residual current detection, the STRO-40L Series enhances safety, reliability, and convenience, making it an indispensable component in modern electrical installations.
