Is this helpful?

725.154 Applications of Listed Class 2, Class 3, and
PLTC Cables.
***
(D) Industrial Establishments In industrial establishments
where the conditions of maintenance and supervision ensure
that only qualified persons service the installation, Type PLTC
cable shall be permitted in accordance with either (1) or (2):

(1) Where the cable is not subject to physical damage,
Type PLTC cable that complies with the crush and impact
requirements of Type MC cable and is identified as
PLTC-ER for such use shall be permitted to be exposed
between the cable tray and the utilization equipment or
device. The cable shall be continuously supported and
protected against physical damage using mechanical
protection such as dedicated struts, angles, or channels.
The cable shall be supported and secured at intervals
not exceeding 1.8 m (6 ft).

(2) Type PLTC cable, with a metallic sheath or armor in
accordance with 725.179(E), shall be permitted to be
installed exposed. The cable shall be continuously supported
and protected against physical damage using
mechanical protection such as dedicated struts, angles,
or channels. The cable shall be secured at intervals not
exceeding 1.8 m (6 ft).

I think the key is that PLTC-ER and PLTC with armor can be installed exposed (at least sort of exposed), but regular PLTC cannot. PLTC-ER exposure limits are just between cable trays and utilization devices, while PLTC with the armor does not have those limits.

I have Belden 1030A which is PLTC and ITC cable. The area the cable would be installed is CLASS I. Would like to know what interval outside the conduit and cable tray can be unsecured or unsupported. Or can this cable be used. Could not find any reference in NEC code about Class I PLTC cable installation.

I don't believe it can be run exposed at all.
