Zero KST200 Water Heater Thermostat – Lower Element, UL Listed, Single Throw 120/480VAC, Adjustable With Safety Switch

About This Product

If your water heater isn't keeping up, this Zero KST200 lower thermostat might be the fix.

It's a single-throw thermostat rated for 120 to 480 VAC, designed for dual-element tanks.

It's got an energy-saving range setting and a built-in safety switch that shuts things down if it overheats – so you're protected from potential damage or danger.

All thermostats are adjustable, and it carries UL certification, so you know it meets safety standards.

Cross-references with the 59T model, so if you're replacing one of those, this is your direct match.

Just a heads-up – make sure you turn off the power before you start working on the water heater, and place the thermostat properly against the tank behind the bracket.
Serious stuff, but it's a straightforward swap for anyone who's done this before.

Reliable, safe, and gets your hot water back.
