It’s 600V. That’s the common insulation class for panel wire

When I hear control wiring I think switchgear, which is normally 600V rated SIS wire.

Is there a table or something where these values can be looked up?

I am not aware of one, but would be interested to know as well.

NEC Table 310.104(A) provides application and insulation ratings for 600V class wire.
NEC Table 310.15(B)(16) provides ampacities.

SIS (insulation rating 90C) is what I would first think to use in most switchgear control wiring applications, but it can vary based on actual need in a substation or switchgear.

Here is a PDF with various tables from NEC Article 310, might be worth a look: https://www.houwire.com/pdf/Article_310-Conductors_for_General_Wiring.pdf
