Abstract
A circuit breaker including a manually operated lever, a movable contact lever for opening and closing the electrical circuit through the circuit breaker, a switch latch which connects the manually operated lever to the movable contact lever and which activates the movable contact lever, a thermal trigger connected to the switch latch and a magnetic trigger, connected to the switch latch. The magnetic trigger, the contact lever, the switch latch and the thermal trigger all occupy separate compartments.
Claims13
A circuit breaker with a manual release comprising:
- a manual lever;
- a movable contact lever means for opening and closing the electrical circuit through the circuit breaker by moving between an opened and a closed position;
- a magnetic triggering means, for sensing severe excess current running through the circuit breaker;
- a toggle joint means, for moving said contact lever means from the closed position to the open position and from the open position to the closed position in response to movement of said manual lever and in response to said magnetic triggering means;
- said toggle joint means being disposed in a substantially straight line between said manual lever and said movable contact lever means, said movable contact lever means being swivably attached to said toggle joint means;
- a hinged armature, connected to said magnetic triggering means;
- a triggering lever, attached to said toggle joint means, for triggering said toggle joint means to cause said movable contact lever to open or close the circuit in the circuit breaker in response to said hinged armature contacting said triggering lever;
- and
- a housing in which the circuit breaker is disposed, having separate compartments for said magnetic triggering means, said movable contact lever means, and said toggle joint means, said magnetic triggering means and said movable contact lever means being disposed laterally from said toggle joint means, said compartment for said movable contact lever means being below said compartment for said magnetic triggering means and forming part of the bottom of said housing, said movable contact lever means being disposed in said compartment substantially parallel to the bottom of said housing;
- and
- wherein said housing has grooves along the length thereof and wherein said toggle joint means further comprises a bow, articulated to said manual lever, a support lever, a pawl articulated to said support lever, a first pin, a second pin, a release lever, said bow, support lever and release lever all being swivelably mounted on said first pin, said pawl being capable of being locked in position by said release lever and being also swivelably mounted on said second pin, said second pin also supporting one end of said movable contact lever means, wherein both pins are displaceably guided in the grooves of said housing in the lengthwise direction.
