ABSTRACT:
A circuit breaker device is disclosed which includes a main contact coupled in parallel with a series combination of a resistor and a resistor contact. The wipe length of the resistor contact is longer than that of the main contact. Means are provided for moving both contacts simultaneously at the same rate in the closing direction such that the main contact closes prior to the closing of the resistor contact. Means are provided for moving the contacts in the opening direction such that the resistor contact moves at a slower rate than the main contact whereby the main contact is opened prior to the resistor contact.
