Abstract

Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

First claim

That which is claimed:

1. An electrical distribution system, comprising:
a housing;
a plurality of circuit breakers held by the housing, each of the plurality of circuit breakers comprising at least one lock-out lock and a trip unit with a display, wherein the at least one lock-out lock is electronically selectively controlled to be moveable to a locked position and to an unlocked position, wherein the locked position is associated with a locked-out state of the circuit breaker associated with an OFF state of non-conduction; and
a dashboard in communication with the plurality of circuit breakers, wherein the dashboard displays status of the circuit breakers as one of:
in a locked-out state;
in an ON state associated with conduction;
in an OFF state associated with non-conduction; or
in a tripped state,
wherein the dashboard is configured to receive a lock-out state signal from a respective circuit breaker when placed in a locked-out state and/or after a position sensor in or on the circuit breaker has verified that the at least one lock-out lock is properly deployed to the locked position.

2. The electrical distribution system of claim 1 , wherein at least one of the circuit breakers is configured to require multiple defined electronic keys to be communicated thereto before electronically directing the lock-out lock thereof to move from the locked position to the unlocked position.

3. The electrical distribution system of claim 1 , wherein the circuit breakers are configured to wirelessly communicate with mobile devices comprising and/or in communication with an APP to control movement of the at least one lock-out lock.

4. The electrical distribution system of claim 1 , wherein the circuit breakers are configured to wirelessly communicate with a mobile device comprising and/or in communication with a lock out tag out (LOTO) APP to control movement of the at least one lock-out lock.

5. A method of operating a current interrupter comprising:
providing a circuit interrupter with an electronically controllable lock-out lock;
electronically receiving at least one defined digital key; then
electronically directing the lock-out lock to move to a locked position associated with a lock out state of the circuit interrupter to block a handle from moving to an ON position associated with conduction; and
displaying a do not operate message on a display of the circuit interrupter when in the lock out state thereby providing a warning tag out alert for the circuit interrupter.

6. The method of claim 5 , further comprising electronically sending a lock-out state signal to a dashboard to indicate a lock-out status of a respective circuit interrupter when in a lock-out state.

7. The method of claim 5 , further comprising electronically receiving at least one digital key before electronically directing the lock-out lock to move from the locked position to an unlocked position, optionally providing the at least one digital key before one or both of the electronically directing steps is carried out using a lock out tag out APP provided at least partially using a mobile device of a user.

8. The method of claim 7 , wherein the electronically receiving at least one digital key before electronically directing the lock-out lock to move from the locked position to the unlocked position requires multiple electronic keys.

9. The method of claim 5 , further comprising electronically generating one or multiple electronic keys that are operable to concurrently direct movement of a plurality of lock-out locks of different circuit interrupters to the locked position or to an unlocked position.
