SKU CH-XC03-NTSBQ MPN FL-2-150A/75MV

DC current shunt resistor rated 150 A with 75 mV drop and 0.5 accuracy class for analog or digital panel meters

  • Accurate current measurement with 0.5 class precision
  • Handles up to 150 A continuous DC current
  • Low 75 mV drop minimises circuit interference
  • Compact 11 x 2.5 x 1.5 cm footprint fits tight panels
  • Works with both digital and analogue ampere meters

What This Shunt Does

This 150A 75mV DC shunt resistor extends the current measuring range of a panel meter. It produces a 75mV voltage drop at full rated current so the meter can display amperes directly. The device works with both digital and analog panel meters. Accuracy is specified as 0.5.

Who Should Use It

Electricians and technicians who need to measure high DC currents with a standard panel meter will find this shunt suitable. It is designed for fixed installations where a 75mV drop is acceptable. Buyers who require a lower voltage drop or a different current rating should look at other shunts.

Deciding Specification

The critical figure is the 75mV voltage drop at 150A; the panel meter must be calibrated for that exact drop. Physical size is 11 x 2.5 x 1.5cm, so the mounting space must accommodate those dimensions.

Questions about this item

Will the 150A 75mV shunt work with my existing analog panel meter?

Yes, the shunt is compatible with both digital and analog meters, providing a 75mV drop at 150A for direct connection to your panel meter's input terminals.

How do I verify the 0.5 accuracy class after installation?

Apply a known DC current up to 150A and measure the voltage drop across the shunt terminals; a reading of 75mV at full current confirms the 0.5 class accuracy.

Does the package include mounting hardware or wiring for the 11 x 2.5 x 1.5cm shunt?

The box contains only the 150A 75mV DC shunt itself; mounting screws, bus bars, and connection cables must be sourced separately.
