Carrier a19abc-24c Temperature Control with Bulb 120/240V

Product Description

The CARRIER a19abc-24c is a temperature control with bulb designed for reliable temperature regulation in HVAC systems. The unit operates at 120/240 volts and is rated at 60 amps, making it suited for both residential and light commercial applications. The bulb-type sensing element provides direct thermal detection, translating temperature changes into control output to maintain consistent system operation. This is an OEM-style replacement part, meaning connectors, sensors, and control logic are built to factory specifications for straightforward installation by qualified HVAC technicians.

The a19abc-24c is intended for use in HVAC systems requiring bulb-type temperature control, including heating and cooling equipment where direct sensing is part of the control strategy. Its dual-voltage rating at 120/240V broadens its range of compatible equipment. Licensed HVAC technicians performing service or replacement work on thermostat and high-limit control circuits will find this part consistent with OEM fitment requirements.
