Abstract

Embodiments of this present disclosure may include a handle disposed on an outer surface of a housing of electrical circuitry. The handle may provide access to at least a portion of the electrical circuitry. The handle may include a status indicator that emits light in response to a control signal from control circuitry. The status indicator may be disposed around the handle. The control circuitry may detect a state of the electrical protection circuitry. The control circuitry may also transmit the control signal to the status indicator based on the state. The control signal may control one or more properties of the light emitted by the status indicator, and thus indicate to an operator the state of the electrical circuitry.

Claims20

Dependent claims

An industrial automation system, comprising:

electrical protection circuitry having a supply side coupled to a power supply and a load side coupled to a load;
a handle disposed on an outer surface of a housing of the electrical protection circuitry, wherein the handle is configured to provide access to at least a portion of the electrical protection circuitry;
a status indicator configured to emit light in response to a control signal, wherein the status indicator is disposed proximate the handle;
and
control circuitry configured to:
verify whether the supply side and/or the load side are energized to determine an operational status of the electrical protection circuitry;
and
transmit the control signal to the status indicator based on the operational status to visually communicate the operational status via the outer surface of the housing.
