<p>A circuit interrupter in electrical capacitors is activated by an interruption mechanism that moves an actuator (44) in response to a predetermined physical condition within the capacitor to cause electrical disconnection. The actuator has a range of motions through a limited number of stable positions and is mechanically pre-biased to move towards one of the stable positions when not already in one of the stable positions. Previously, pressure sensitive interrupters would be reconnected when the cover and terminals settled back due to pressure drop which could cause arcing. The present capacitor (12) is quickly and effectively disconnected when pressure builds up and stably remains in its popped up position to reduce the chance of reconnection. Capacitor terminals (18 and 20) are mounted on the actuator which is attached to a housing (54) by hinge regions (58) which provide a stable position upon build up of a pressure.</p> |
