HAIPART: Precise Protection and High-Reliability Power Distribution Solutions 


HAIPART, a professional manufacturer of low-voltage electrical MCB parts, utilizes high-quality materials and precision manufacturing processes to produce high-performance, high-reliability MCB components, providing stable protection for industrial, commercial, and residential power distribution systems. Our MCB assemblies, with their excellent breaking capacity and stability, are a core choice for power distribution safety.


Key Advantages

Precise Protection Mechanism: Employs thermal-magnetic dual tripping technology. Thermal tripping handles overloads, while magnetic tripping handles short circuits, achieving graded protection. In the event of a short circuit, electromagnetic tripping can disconnect the circuit in milliseconds, preventing equipment damage.


High Safety and Reliability: Built-in arc separator and arc-extinguishing design significantly reduce fire risk; supports AC 240/415V and DC 220V, providing wide voltage adaptability to various circuit environments.


Flexible Application Scenarios: MCB accessories with a width ≤20mm can be combined into multi-pole circuit breakers, suitable for residential, commercial, and other terminal power distribution applications; offers breaking capacities from 10KA to 16KA to meet different short-circuit current requirements. 


Application Areas

HAIPART's MCB components are widely used in residential and commercial buildings, as well as industrial and special applications, making them an ideal choice for power distribution systems due to their precise protection, high security, and flexible application.
