Shunts

Shunts, also called shunt resistors or ammeter shunts, are precision electrical components designed to measure high electrical currents. They work by allowing the majority of the current to bypass the measuring instrument (typically an ammeter or a voltmeter connected across the shunt's terminals). These resistors are commonly used in conjunction with ammeters, power monitoring systems, and control circuits to ensure accurate current readings, especially in high-current environments. Their robust design, high durability, and reliable performance make them essential in both industrial and commercial applications.

Why Buy Current Shunts?

You should consider buying current shunts for several key reasons. These devices enable the measurement of currents that would otherwise exceed the capacity of standard ammeters, protecting these sensitive instruments from damage. They are a cost-effective solution for high-current measurement compared to specialised high-current ammeters. Additionally, investing in a shunt provides accurate and reliable current readings. 

View Our Quality Shunt Resistors:

We offer best-in-class ammeter and multimeter shunts known for their precise accuracy. Our selection includes:

• Brass-Ended Shunts – a brass-ended shunt provides excellent electrical conductivity and facilitates secure connections. These current shunts are typically designed for moderate to high current applications and offer a good balance of performance and durability.   
• Plate Shunts – Characterised by their flat, heavy-duty metallic plates, these shunts are designed to dissipate heat efficiently. They are a compact and reliable solution for demanding current measurement scenarios, often found in industrial power supplies, welding equipment, and heavy machinery.
