The HTR15181 is a crankcase heater that has a power rating of 575V and 40W with a 6.5" diameter measurement.
What is a Crankcase Heater?
The crankcase heater's function is to provide heat that warms up the liquid refrigerant. This prevents the condensing and migration of the refrigerant from going into the system where it shouldn't be.
A crankcase heater's sole purpose is to prevent refrigerant migration and mixing with crankcase oil when the unit is off, and to prevent condensation of refrigerant in the crankcase of a compressor. The crankcase heater keeps refrigerant at a temperature higher than the coldest part of the system. So to describe it as 'self-regulating' is a bit misleading. Yes, in a sense, it regulates automatically as that is its purpose.
