Industrial ACB-2UA79W Low Pressure Control Switch

ACB-2UA79W is a cartridge‑style low‑pressure control switch from the Danfoss ACB family, designed to monitor refrigerant pressure on the low side of HVAC and refrigeration systems and to actuate an electrical circuit when a selected pressure threshold is reached. As a replaceable cartridge sensor, it provides safety and control functionality in commercial refrigeration equipment, air‑conditioning condensers, and heat pumps, helping protect compressors from low‑pressure conditions and enabling automatic start/stop logic tied to evaporator pressure. The ACB line is built for integration with standard Danfoss controls and mounting configurations, with the 2UA79W variant positioned among the low‑pressure options used across condensers, evaporators, and expansion‑valve assemblies. When selecting this part, consider compatibility with your system’s electrical rating and connection style, as well as the manufacturer’s documented operating range and installation guidelines specific to the 2UA79W model. For exact electrical specifications, pressure setpoints, and fitment details, refer to the official Danfoss datasheet for ACB/CCB cartridge switches and confirm with your distributor or service partner to ensure proper integration with your equipment.
