Measuring Shunts Selection Guide: Technical Criteria & Application Standards
Measuring Shunts selection guide: technical parameters, mounting and compliance standards, and Tense comparison.
A measuring shunt is a precise, low-resistance measuring resistor that creates a small voltage drop proportional to the current passing through it. It is used in battery banks, rectifiers and DC distribution panels to measure high direct current with a millivolt-input ammeter connected to the shunt terminals. This category includes Tense DC shunts with the SNT60 code and a 60 mV output; rated currents such as 30 A, 100 A, 250 A, 600 A and 1000 A are listed. Select the shunt by a rated current that covers the highest continuous current of the line, a millivolt value identical to the ammeter input, and the connection dimensions. With these shunts, 60 mV appears across the terminals when the rated current flows; the shunt setting on the ammeter must be made according to the rated current of the shunt and this voltage. A measuring shunt is not a current transformer; it is connected in series in the main current circuit and does not isolate the measuring circuit from the main circuit. The Measuring Shunts category on Welibaba includes 11 active models from leading manufacturers such as Tense.
Key Technical Parameters for Selecting Measuring Shunts
To specify the right Measuring Shunts model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Rated Current | 100 A, 1000 A, 150 A, 1600 A | Verify against project schedule and load calculation |
| Output Voltage | 60 mV | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Measuring and Control Devices.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Electric Energy Meters, Energy Measurement Accessories, Ammeters.
