Ranco A30-311 Refrigeration Temperature Control with Capillary - 42

The Ranco A30-311 is a constant differential temperature control designed for commercial freezer and ice machine applications. This adaptable control switches electrical components in refrigeration systems in response to sensed temperatures, providing reliable temperature management for demanding commercial environments.

Key Features:

• Single-pole, single-throw (SPST) switch configuration
• 42-inch vapor-filled capillary sensing element
• Temperature range: -22°F to 23°F (cold off at -22°F)
• 14°F fixed differential for consistent temperature control
• Laser-welded stainless steel bellows construction
• High-amperage contacts for reliable switching
• Includes break-off shafts and mounting brackets for fast installation
• Standard 1/4-inch quick-connect terminals

The A30-311 is part of Ranco's A30 Series of adaptable constant differential controls, manufactured by Robertshaw. It features a compact design that mounts easily to most commercial refrigerators, freezers, and ice machines. The pneumatic action provided by the vapor-filled capillary ensures accurate temperature sensing and control. Ideal for applications requiring precise low-temperature control in commercial foodservice and refrigeration equipment.
