Electric Current Measure Manganin Shunt
Products Description
This Electric Current Measure Manganin Shunt is not a single-material stamped part, but a composite metal structure component based on a functional zoning design concept:
Middle Functional Zone: Manganin Alloy
As the core area for current detection, it undertakes the main resistance function, ensuring the linearity and stability of current-to-voltage conversion.
Two-End Connection Zone: High-Conductivity Copper (Cu)
Used for welding, riveting, or insertion, reducing contact resistance and improving the reliability of the overall current path.
The manganin and copper are metallurgically joined at the strip stage using electron beam laser welding, followed by continuous stamping, achieving a high degree of uniformity between electrical and structural performance within a single component.
Product Nature and Core Features
Laser-Laser Composite Bimetallic Structure
Utilising electron beam laser welding technology, copper and manganese copper strips are firmly fused, forming a gapless, weld-free metallurgical bond layer. The bimetallic structure synergistically leverages the "precise resistivity of manganese copper + efficient heat dissipation of copper," balancing measurement accuracy and heat dissipation requirements.
Dedicated Adaptation for Magnetic Latching Relays
Customised stamping dimensions and structures are provided according to the current rating, installation space, and operating environment of the magnetic latching relay. Single stamped parts or integrated components are available, precisely matching the internal assembly requirements of the relay without secondary processing.
High-Precision Current Measurement Attributes
The manganese copper material uses high-purity raw materials with an extremely low temperature coefficient of resistance, ensuring precise and controllable resistance values. Stable conversion can be achieved over a wide current range, with measurement errors controlled within stringent limits, guaranteeing accurate current signal feedback.
High stability operation characteristics
The laser composite structure has high connection strength, which can resist the vibration and shock generated by the frequent operation of the magnetic latching relay. It also has excellent temperature and humidity resistance, and there is no performance degradation during long-term operation under complex power conditions.
Main Functions: Multi-dimensional Support for Precise Operation of Magnetic Latching Relays
Precise Current-to-Voltage Conversion Function
Utilising the high-stability characteristics of manganin resistors, the large current carried by the magnetic latching relay is precisely converted into a linearly changing, small voltage signal. This voltage signal can be accurately acquired by the detection circuit, enabling real-time monitoring and measurement of the relay's operating current, providing reliable data for precise control.
01
Overload and Overcurrent Protection Function
When an overload or overcurrent fault occurs in the magnetic latching relay, the voltage signal output by the shunt will simultaneously exceed the normal range. After the detection circuit detects this abnormal signal, it can quickly trigger the relay's protection mechanism to disconnect the circuit, preventing the relay from burning out or downstream equipment from damage due to overcurrent, thus ensuring the safety of the power system.
02
High-efficiency heat dissipation and stable operation
Through a copper-manganese copper composite structure design, heat generated during current flow is quickly dissipated, preventing resistance drift and performance degradation caused by overheating of the shunt itself. Simultaneously, the robust laser-coated structure resists vibration and environmental changes, ensuring stable operation of the shunt throughout the entire lifespan of the magnetic latching relay and reducing maintenance costs.
03
Dedicated adaptation function for magnetic latching relays
Customised size and structural design precisely adapt to the internal installation space and assembly process of different magnetic latching relay models, eliminating the need for secondary processing by the customer. The lightweight and miniaturised structural design aligns with the miniaturisation trend of magnetic latching relays without compromising the relay's electromagnetic performance and operational reliability.

Design Advantages: Performance Optimised by Structure
Maximised Heat Dissipation Area
Manganin Shunt for Electricity Meters are typically designed with heat dissipation fins or enlarged edges. Considering the thermal effect of the current, we increased the contact area with air through structural design, accelerating heat dissipation and preventing the shunt from becoming a heat source inside the relay.
Stress Relief Structure
Rounded corners and buffer grooves were designed at the bends of the stamped parts to prevent the mechanical stress caused by thermal expansion and contraction from being transmitted to the manganese-copper area, thereby avoiding resistance drift.
Multi-Pin Design
To accommodate different PCB board sizes or current transformers, we designed various pin configurations for easy automated insertion or soldering. The pins are made of copper, resulting in fast soldering and full solder joints.
