Contact Resistance Measuring Device T-μM50
Contact Resistance Measuring Device T-μM50
A Dependable Device to measure the contact resistance of various kinds of switches
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.
SALIENT FEATURES
- 1/ Compact, Light-weight and Easy to transport.
- 2/ Two input voltages, i.e. AC 100V and AC 200V, available.
- 3/ Different types of connectors to avoid miss-connections of external connection cables.
- 4/ Since the output current is fixed at 50A and the contact resistance is indicated in terms of the voltage drop of the contact resistance, the device is very simple and robust, rendering it very competitive and it's accuracy very high.
- 5/ The output current is automatically cut off if the current conducting time exceeds 30 seconds.
