It is possible to summarize and display/print the measurement results for three phases! A low-resistance measuring device designed for easy use on-site.
This product is designed to measure the contact resistance of the main contact parts of power circuit breakers, etc. It flows a DC 10A current through the contact parts and calculates the resistance value using the four-terminal method. Circuit breakers may have bushing current transformers installed, but to prevent transient phenomena during the ON and OFF states of the energized current, the increase and decrease of the energized current is done gradually. 【Features】 ■ Gentle measurement for circuit breakers (gradual increase and decrease of energized current) ■ Display and printing function for measurement results ■ User-friendly shape for field use
