A device (100) for interrupting the flow of electricity in a circuit, the device being configured for mounting in a cutout (102) coupled to the circuit, including a first external electrical contact (126) and a second external electrical contact, the first and second external electrical contacts being coupled to a vacuum interrupter (152) disposed within an housing (120) of the device (100), the vacuum interrupter (152) having a first contact movable relative to a second contact for making or breaking an electrical circuit between the first external electrical contact (126) and the second external electrical contact and responsive to a force exerted upon the first contact by an actuator (172, 300, 400) coupled to the first contact, the device having a trunnion (122) for engaging a hinge portion (112) of the cutout (102), the trunnion (122) formed with motion limiting structures (210) that engage the hinge portion (112) upon dropout of the device (100) from the cutout (102) to limit rotation of the device (100) within the hinge portion (112). |
