Remote Shutoff Device for Circuit Protector Switch

A remote shutoff device for a circuit protector switch comprising a shaft, the remote shutoff device comprising:

• a gear comprising a plurality of outer teeth, the gear configured to be coupled to the shaft of the circuit protector switch and to rotate with the shaft on an axis;
• a spring-loaded lever assembly comprising an arm, wherein the arm comprises a first end and a second end, the second end comprising a plurality of inner teeth that are engageable with the plurality of outer teeth of the gear;
• an actuating assembly comprising a latch;
• and
• a reset mechanism coupled to the spring-loaded lever assembly;
• wherein the remote shutoff device is operable to be armed or disengaged, wherein the reset mechanism is configured to reset the remote shutoff device from disengaged to armed, wherein when the remote shutoff device is armed:
• the spring-loaded lever assembly is latched by the actuating assembly in an extended position, and
• the circuit protector switch is operable between an ON state and an OFF state.
