<p>An overcurrent protection device 10 has a fixed 26 and a movable 32 contact electrically connected to a pair of terminals 14, 16 and a snap acting bimetallic member 34 which is responsive to a thermally resistive element 28, connected in series with the contacts between the terminals to cause the contacts to move from an engaged position to a disengaged position. The device further includes a current bypass path 24 adapted to be connected in parallel with the thermally resistive element 28 and a second thermally responsive bimetal member 24b to cause the electrical connection. Additionally, a heater block 18 can be provided between the terminals 14, 16 which has a resistance significantly higher than that of the thermal resistive element 28. <IMAGE></p> |
