This read-write integer sets the user-defined low-load current threshold, in Watts according to this MIB's description, for a given metered outlet on a chained Rack PDU. An admin sets it to catch an unexpected drop in that specific outlet's power draw, which can indicate the connected device lost power or shut down. For example, setting this threshold low on an outlet feeding a server that normally draws steady power would raise a warning the moment that server's actual draw collapses toward zero.
