EBW Manganese Copper Shunt For Relay
Products Description
The EBW Manganese Copper Shunt for Relay is a precision current sampling element specifically designed for magnetic latching relays. It achieves a metallurgical-grade bond between dissimilar metals using electron beam welding with T2 high-purity copper conductive terminals, ensuring an extremely low temperature coefficient while perfectly combining milliohm-level precision resistance with hectoampere-level current carrying capacity. As a key component for signal acquisition and current measurement in power metering systems, this shunt directly determines the metering accuracy, long-term stability, and temperature rise performance of the energy meter.
Material Advantages
Manganese copper
Temperature coefficient of resistance ≤ ±50ppm/℃, annual stability ≤0.01%, making the Magnain Shunt Resistor Shunt suitable for high-precision current measurement.
T2 copper
Conductivity ≥98%IACS, tensile strength ≥200MPa, the Mangnetic Latching Relay Shunt exhibits strong corrosion resistance.
Composite Structure
The Latching Relay for Smart Energy Meter utilizes a composite structure of manganin and copper, achieving an optimal balance between constant resistance and high conductivity.
Product Application Advantages
| Optimized Overall Meter Costs | The Manganin Shunt Resistor for Electrical Meters utilizes an integrated stamping and electron beam welding mass production solution. Compared to the separate assembly of shunt components, this reduces assembly time and helps meter manufacturers cut labor costs on production lines. |
| Improved Overall Metering Stability | The stable resistance and welding performance of the shunt reduce the meter's factory failure rate and lower after-sales repair costs. |
| Adaptability to Multiple Project Scenarios | The same basic structure can be adapted to various scenarios, including residential, commercial, industrial, and energy storage applications, through minor adjustments to dimensions and resistance. Shunt's supporting requirements shorten customers' new product development cycle. |
Comparison with competitors' advantages
Process compared to ordinary brazing products
Ordinary tin brazing relies on solder to bond dissimilar metals; under high-temperature conditions, solder creep and oxidation can cause resistance drift. This product uses electron beam metallurgical fusion without solder, resulting in stronger resistance stability over long-term use and compatibility with high-end metering equipment.
Cost compared to hand-soldered products
Automated mass production with proprietary progressive dies reduces unit processing costs compared to hand-soldered products, offering a significant price advantage for bulk purchases. Furthermore, the quality consistency of the Maganin Shunt Resistor Shunt is far superior to manual operations.
Compared to products from intermediaries
Direct factory sales eliminate intermediaries, allowing direct contact with engineers for in-depth customization of the Latching Relay with ODM for the Three Phase Energy Meter. Trading companies without their own production lines cannot undertake such in-depth modification and development.
Compared to products from unlicensed small factories
Our entire series of Latching Relay for Smart Energy Meter products has a full set of environmental and system certifications. Products from small factories often lack RoHS and REACH testing, posing a risk of customs seizure for customers exporting complete units.
