Description
Product Positioning
This circuit breaker is specifically designed for residential use, including apartments, villas, and houses. It serves as a fundamental protection unit in the home power distribution system, safeguarding branch circuits for lighting, sockets, kitchens, bathrooms, and air conditioning. Compliant with the IEC/EN 60898-1 international standard, it ensures stable operation in AC environments and meets the long-term safety requirements of households. When used in conjunction with a residual current device (RCD) module, it provides triple protection against overload, short circuits, and electric shock, offering comprehensive home electrical safety.
Materials and Craftsmanship
The casing is made of flame-retardant reinforced engineering plastic, offering excellent heat resistance, impact resistance, and insulation. It has undergone rigorous testing and remains stable without deformation or fire hazards during long-term use.
Internal conductive components are made of high-conductivity alloy and precision-machined to reduce heat generation and ensure stable current transmission. The arc-extinguishing system is optimized for rapid fault arc interruption, preventing fault escalation. This breaker is DIN-rail compatible, and the terminals support a wide range of wire specifications, enabling secure and convenient installation.
Core Advantages
Utilizes mature thermomagnetic double tripping technology:
Overload protection with inverse-time tripping (higher current causes faster trip)
Instantaneous short-circuit protection
Effectively prevents overheating, appliance burnout, and electrical fires.
Tripping characteristics are matched to household appliances, ensuring precise operation without nuisance trips, protecting devices like refrigerators, TVs, and lighting.
Excellent electrical and mechanical lifespan, withstanding frequent switching and fault disconnections.
Compact and aesthetically designed, saving space and complementing modern home décor.
Application Value
This cost-effective circuit breaker provides reliable and consistent protection for families. It can function as the main household switch or protect high-risk areas such as kitchens and bathrooms. It is an ideal solution for home renovations, property upgrades, and new building projects, enhancing overall household electrical safety.
