Contact Resistance Measuring Device

modelT-μM 10
Contact Resistance Measuring Device
T-μM 10/T-μM 50/T-μM 100

This device measures the contact resistance of a circuit breaker, disconnecting switch or various kinds of switches by the four-terminal method. The voltage drop of the contact resistance is measured and indicated by conducting 50A d.c. current through the conductor of which the contact resistance is to be measured.

Wiring・Inspection Task

Edge freewrappingbit
Edge-Free Wrapping Bit
Because of its high reliability, wire wrapping has been adopted in diverse fields. However, current wire wrapping methods leave an “edge” at the end of the wire that needs to be cut using tools, a process that is cumbersome and time consuming. Edge-free wrapping bit allows the wrapping to be completed with a smooth end that does not require post-operation care or after inspection, simplifying the whole operation.
