Description
Product Positioning
This product is a hybrid solution designed for scenarios requiring high safety, reliability, and compact installation. It provides protection levels comparable to molded case circuit breakers while fitting within the dimensions of a miniature circuit breaker. Designed according to IEC 60898 and IEC 60947-2 standards, it combines the convenience of residential miniature circuit breakers with the stability of industrial molded case breakers.
It is particularly suitable for applications with strict requirements for space, durability, and safety. In addition to basic overload and short-circuit protection, it offers enhanced shock resistance, vibration resistance, and high-temperature performance.
Materials and Manufacturing Process
The housing is made of high-strength, modified flame-retardant plastic, offering superior mechanical strength, insulation, and heat resistance compared to standard miniature circuit breakers. This ensures structural integrity and stable performance in demanding environments.
The internal mechanism is reinforced, with wear-resistant materials and precision machining applied to contacts, linkages, and tripping components, improving lifespan and operational consistency.
The arc-extinguishing system uses a multi-stage structure for rapid interruption of fault currents, reducing the risk of electrical accidents. Its compact design allows direct replacement of conventional miniature circuit breakers without requiring additional installation space.
Core Advantages
Stable and reliable protection, with rapid response to overloads and short-circuits.
Suitable for various loads, including wiring circuits, motors, lighting, and control systems.
Strong anti-interference performance, operating reliably in complex electromagnetic environments and wide temperature variations.
Excellent current-limiting capability, minimizing the impact of faults on power systems and connected equipment.
Application Value
Ideal for intelligent buildings, industrial equipment, new energy power distribution, communication cabinets, transportation facilities, and commercial complexes. It provides a compact, integrated protection solution that enhances safety, reliability, and operational efficiency compared with ordinary miniature circuit breakers.
