The Field Circuit Breaker HPB45M-82S DS4 is a protection device used in generator field circuits of steam turbine power plants. It is built with a metal alloy housing that incorporates copper conducting components and thermoset or thermoplastic insulating elements. The breaker provides over‑current and short‑circuit protection to maintain stable operation of rotating machinery. It is supplied by Deyang Dongfang Yoyik Engineering Co., Ltd. in China.
The metal alloy conforms to typical engineering grades used for high‑stress electrical enclosures. Copper conductors are standard for low‑resistance current paths, while the insulation class is typically Class B, suitable for temperatures up to 130 °C. The device normally complies with IEC 60947‑4‑1 standards and operates within a typical temperature range of - 40 °C to +85 °C. Typical dimensions are about 150 mm × 120 mm × 200 mm and the unit weighs roughly 12 kg.
The breaker is most often specified for turbine retrofit projects, plant‑maintenance procurement and other power‑generation infrastructure upgrades. Plant engineers and EPC contractors are the principal buyers, and they should confirm minimum order quantities and delivery lead times directly with the supplier. Incoterms, payment conditions and any required certifications must be verified before placing an order.
