Abstract

An apparatus includes an enclosure, a power switch, an absence of voltage detector controller, and an absence of voltage detector. The power switch is mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line is configured to transfer the electrical power outside of the enclosure to an industrial control panel. The absence of voltage detector controller is configured to determine a presence and an absence of each of a plurality of phases of the electric power on the load-side power line inside the enclosure. The absence of voltage detector is visible from external to the enclosure, has a switch, and is configured to illuminate one or more lamps indicating the absence of the electrical power on a corresponding one or more of the plurality of phases in response to a pressing of the switch.

Abstract

An apparatus includes an enclosure, a power switch, one or more power converters and a wire. The enclosure may include a door. The power switch may be mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line may be configured to transfer the electrical power outside of the enclosure to an industrial control panel. The one or more power converters may be configured to generate a low-voltage electrical power from the electrical power. The wire may be configured to transfer the low-voltage electrical power outside of the enclosure.

Abstract

An apparatus includes an enclosure, a power switch, one or more power converters and a wire. The enclosure may include a door and one or more apertures. The enclosure may be mechanically attachable to an external side of an industrial control panel with the apertures aligned to one or more openings in a wall of the industrial control panel. The power switch may be mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line may be configured to transfer the electrical power through at least one of the apertures. The power converters may be configured to generate a low-voltage electrical power from the electrical power. The wire may be configured to transfer the low-voltage electrical power through at least one of the apertures.

Abstract

An apparatus includes an enclosure, a power switch, a cable actuator, a power converter and a manual switch. The enclosure may be mechanically attachable to an external side of an industrial control panel. The power switch may be configured to switch electrical power. The cable actuator may be configured to control the power switch and may have an end connectable to a power disconnect handle of the industrial control panel. The power switch may be open while the power disconnect handle is in an off position and closed while the power disconnect handle is in an on position. The power converter may be configured to generate low-voltage power from the electrical power. The manual switch may be configured to switch the electrical power from a line side of the power switch to the power converter. A wire may transfer the low-voltage power through at least one aperture.
