Operating mechanism of a low voltage electric circuit breaker |
摘要 |
A multi-pole circuit breaker having a molded case and a contact operating mechanism supported in said case. The mechanism is controlled by a handle and a trip device. To obtain the reset of the trip hook when said trip device has opened the contacts, a rocker secured to the handle engages a drive lever forming an extension of the upper link of a toggle joint of said mechanism. The catch of the trip device is biased into an intermediate balanced locking position by means of a spring and is positioned onto a pivot pin by means of radial projection insides the bore of the catch which fits into a matching groove of the pin.
