Can the low voltage safety switches be installed to a high voltage application? Why does the safety switch have a “only low voltage” tag on it?

Most safety switches are wired into a low voltage thermostat to shut down the HVAC system that produces the condensate. This safety switch activates when high water is detected. 1502C & 1502UR max voltage rating is 250 volts, 1502S max voltage is 24 volts
