What are the Electric Meters Manganin Shunts?
Electric Meters Manganin Shunts are key passive parts built for high‑accuracy current sensing in single‑phase and polyphase metering systems. They convert primary line currents into proportional millivolt signals. Made of premium copper‑manganese alloy and high‑conductivity C1100 copper terminals, they feature low TCR and minimal thermal electromotive force for reliable thermal stability.
As a direct‑supply factory serving global electrical brands and R&D engineers, we are equipped with precision stamping equipment, high‑vacuum electron‑beam welding machines and automated resistance sorting stations. Mass‑production can reach tolerance as tight as ±0.5%. We offer full OEM service covering custom terminal shapes, non‑standard resistance values and special mounting structures. Our IATF 16949‑compliant quality control satisfies strict metering and supply‑chain requirements.
