Will this protect poe++ or just poe+?

From the manufacturer's website Nominal PoE Voltage <60 V Maximum continuous current 1.2 A Therefore you should be able to get 60 watts continuous, or Type 3 PoE++

What is a "gas discharge tube", and what is its function in this device?

A gas discharge tube is basically a over voltage protector. It is an open circuit until impinging high voltage enters an ionizes the gas inside which creates a low impedance presumably to ground. Only useful in a lightning incident (nearby or direct hit). If the latter then you are fundamentally screwed. I have photos to probe it. Message: if lightning is near (or predicted) then simply disconnect everything. Let us ALL float. I’m talking antennas, AC power cord and ground wires

Does this device support 24v passive poe?

YES , this will easily support 24volt passive or non-passive POE. Normally POE is 48volts on power injectors or network switches. I know that it will support over 60 volts, as to smart 3 lens outdoor cameras that i have installed at Banks. This is , if you ground the DIN rail correctly to allow gas discharge tube to function properly to protect equipment. Gas discharge tube opens and closes data circuit, with no ground it will just act as a fuse and burn up after lightning strike. I always use TWO ethernet surge protectors , one on network switch rack and one upon entry into building with both TWO DIN rails grounded. Daniels Data Inc. - Dallas,TX - John Daniels

How long of a rail do you need? What is the shortest length that I can use?

It mounts perpendicular to the dinrail so about 1” is minimum. I’d use enough too have two acres in the rail though or it will rotate.
