High Current Test Probes

Current flows of up to 35 amps for load and functional testing of power components such as semi-conductors, solenoids, loaded PCBs, bus-bars, wound components and batteries. This range shares identical dimensions and will readily intermix with the PA3 - PA7 series and the PC8 series respectively.

This range of probes can be used for load and functional testing of power components such as semiconductors, solenoids, loaded PCBs, bus-bars, wound components and batteries. They share identical dimensions and will readily intermix with the PA3 series general purpose test probes.
