Import 400v-126kv Current Breaker — Buy in Bulk from Supplier in China

The 400V-126kV current breaker from Ningbo Huayuan Electric And Machine Industry Co.,Ltd. is a medium to high voltage circuit protection device engineered for industrial power systems. It covers a wide operational voltage spectrum, from low-voltage 400V applications to high-voltage 126kV networks, with rapid circuit interruption to prevent damage from overloads or short circuits. The unit is designed for both indoor and outdoor installations, with a focus on durability under industrial-grade conditions.

Constructed with high-strength insulating materials and robust mechanical components, this breaker meets standard industry requirements for dielectric strength and thermal endurance. Typical medium-voltage breakers in this class use SF6 or vacuum interruption technology, with standard interrupting ratings of 25kA to 40kA at 126kV. The enclosure is usually IP65-rated for outdoor use, while indoor variants often conform to IP4X or better for dust and moisture resistance.

This breaker is primarily used in power distribution networks, substations, and industrial plants where reliable protection of transformers, generators, and switchgear is critical. It is sourced from Ningbo, Zhejiang, a major hub for electrical equipment manufacturing in China. Buyers typically confirm compatibility with existing switchgear, interruption medium (SF6, vacuum, or air), and whether the unit includes auxiliary relays or remote control interfaces. Packaging for international shipment is standardised to prevent mechanical damage during transit.

Ningbo Huayuan Electric And Machine Industry Co.,Ltd. is based in Ningbo, Zhejiang, at 323 Ningchun Road, a region known for its concentration of electrical and machinery manufacturers. The company operates as an importer-tier supplier with a focus on electrical equipment, including circuit breakers and switchgear components. Its listed address places it within an industrial zone that supports large-scale production and export logistics.

The supplier’s profile indicates a harbor trust tier, which typically reflects a baseline level of verification for export readiness. However, the response rate and average response hours are currently recorded at zero, suggesting that direct communication may require follow-up through alternate channels. The company does not list specific certifications, client references, or production capacity in the provided data, so buyers are advised to request these details directly.
