In one embodiment, there is a fault interrupter device comprising at least one sensor comprising at least one first transformer having at least one outer region forming an outer periphery and at least one inner hollow region. There is also at least one second transformer that is disposed in the inner hollow region of the at least one first transformer. The transformers can be substantially circular in configuration, and more particularly, ring shaped. In another embodiment there is a rotatable latch which is used to selectively connect and disconnect a set of separable contacts to selectively disconnect power from the line side to the load side. The rotatable latch is in one embodiment coupled to a reset button. In at least one embodiment there is a slider which is configured to selectively prevent the manual tripping of the device.

This disclosure relates to various embodiments of lockout relay devices. In one embodiment, a lockout relay device may transition between a closed position and a lockout position in response to an action of a deck device. The lockout relay may further be configured to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation. A manual actuator may permit a manual transition of the lockout relay device from the closed position to the lockout position and from the lockout position to the closed position. A lockout mechanism may be configured to cause the lockout relay device to transition to the lockout position in response to the force generated by the deck device. The lockout relay device may remain in the lockout position until the occurrence of one of a manual adjustment and a reset operation.

A load break cutout refuser includes an actuator configured to couple to a fuse cutout. A receiver is communicatively coupled to the actuator. The receiver is configured to receive a signal from a transmitter remote from the receiver. The actuator is configured to close the fuse cutout in response to the signal received by the receiver. A system includes the refuser and a transmitter remote from the fuse cutout, receiver, and actuator to send a signal to the receiver to cause the actuator to close the fuse cutout. A method of closing a fuse cutout using the load break cutout refuser system is also disclosed.

An escutcheon module for a circuit breaker includes an escutcheon body configured to seat against a switch face of a circuit breaker. One or more attachments of the escutcheon body are configured to engage with one or more attachment points of the circuit breaker. The escutcheon body can add functionality to the circuit breaker, such as a USB connectivity, Bluetooth connectivity, or Wi-Fi connectivity. The escutcheon body can be of a color the same as or different from the color of the breaker housing. It is also contemplated that the escutcheon body can include a receptacle for a physical lock for locking a switch of the circuit breaker.
