The 5SY4314-8: At 0.3 A, this is a protection device for low-current control circuits, not branch power.
Combined terminals top and bottom, touch-protected, sealable — the sealable feature matters if the panel requires lockout/tagout provision or inspection authority locking.
The higher 35 kA rating applies under the industrial standard, giving headroom for panels with high available fault current.
