Carrier Products Unlimited 3100-20Q1528 Contactor

Carrier HN52SA033 2-pole contactor with a 24 VAC coil, cataloged as 3100-20Q1528, is a compact HVAC switch that carries up to 30 A (30 FLA) at 50/60 Hz to control the condenser compressor and related loads. This two-pole device is designed for standard Carrier systems and other equipment that require a 24 V control signal, making it a common replacement part in residential air conditioners and heat pumps. The 24 VAC coil provides reliable actuation from typical thermostat or control board circuits, and the unit’s two main contacts handle the compressor and fan circuits with compatible terminal spacing for straightforward installation. When energized, the coil pulls in the armature to close the main contacts, enabling the compressor and condenser components to engage; when de-energized, the contacts open to de-activate those loads. With its documented 50/60 Hz coil, the contactor supports operation across regional power standards, and its dual-pole design allows simple, consolidated control of two separate circuits from a single relay.
