Description
The Carrier HH12ZA211 is an Automatic Limit Switch that is used in HVAC equipment like air handlers and furnaces. An electrical safety gear that switches off circuits when there is heat build-up. It has a settable temperature range which is normally between 170°F and 210°F. This is because once the internal temperature rise goes past this level, the heater power is cut off by the thermal switch leaving the dangers of overheating and harm to the furnace or air handler pinned. This safety feature acts as the security of the Carrier HVAC system and as a safety measure.
