Common Questions

Is the Robertshaw 5300-651 suitable for high-voltage applications?
Yes, this unit is rated for up to 480V AC (20 Amps) and 277V AC (30 Amps), making it compatible with most industrial and commercial electrical configurations.

What is the function of the "Open-High" operation?
The Open-High (Direct Acting) configuration means the contacts open when the temperature rises to the set point, effectively cutting power to the heating element to maintain the desired temperature.

Can this thermostat be used in moist environments?
While the 5300 series is rugged, for high-moisture or high-dust areas, professionals should verify if a plastic-coated capillary version is required; however, the standard copper/stainless construction is built for standard commercial kitchen ambient temperatures up to 200°F.
