Three phase, 208 V motor contactor. The coil control circuit is provided by two of the three phase legs interrupted by a remote relay.

Are those control wires running back to the relay Class 1? Can they be run through conduits or enclosures with power limited fire alarm conductors?
 
They are motor control circuits but treated as a Class 1 circuit and cannot be in the same raceway or cable with power limited fire alarm circuit.
 
If there was separate overcurrent for the coil ckt it would be an article 725 class 2 ckt (2020 nec). But I don’t know if class 2 ckt can be run with PLFA

I have never installed a motor stater with a Class 2 circuit from a control power transformer. All of them that I have worked on were Class 1 because the secondary voltage of the CPT has been 120 volts.
 
I've worked on some garage door openers where the coil voltage is 24V for the motor contactor. Other than that I can't think of any. I did have some used 3 phase magnetic motor starters that had 24V coils in them, no idea what the original application was. I remember having to change the coils when I used them

Yes, but Class 2 is limited to 100W, so at best, 208V would be 1/2A, which, if the contactor is big, may not cut it.

Technically, 725 says that a Class 2 circuit must come from a Class 2 power source and I’m not sure if just having a fuse that limits it to 100W (1/2A) qualifies.

Chapter 9, Table 11A limits the current of a Class 2 circuit with a voltage of over 30 volts to 0.005 amps.
