SCCR for different supply voltages to a control panel

[ex protector]

Hello,
I have a control panel with two independent supply voltages (480VAC and 120VAC for a Ex p controller from Bebco)
480VAC enter the cabinet direct to a contactor. Fuse elsewhere outside. After the contactor it is wired to a frequency converter and a power supply 24 VDC (both are fused.).

Do I have to label the SCCR for both supply voltages? Is it okay, to wire the supply cable direct to the contactor? No fuse needed, after cable enters the cabinet?

Kind regards

You only to worry about power circuits. The 120V supply might well be a class 1 circuit if it is the UL labeling you are worried about. The Bebco should come with a SCCR rating already if it needs one. It is separate from the control panel rating.
