Ranco A30-313 Commercial Refrigeration Temperature Control SPST Capillary - 42

The Ranco A30-313 is a commercial-grade cold control temperature switch designed for reliable temperature regulation in commercial refrigerators, freezers, ice machines, and beverage coolers. This constant differential temperature control features a single-pole, single-throw (SPST) switch configuration that operates electrical components in response to sensed temperatures.

Key Specifications:

• Temperature Range: -20°F (cold off) to 21°F (warm on)
• Differential: 8°F constant differential
• Capillary Length: 42 inches with vapor-filled sensing element
• Contact Rating: 20 Amps at 240 VAC, SPST open on low
• Construction: Laser-welded stainless steel bellows for durability
• Mounting: Break-off shafts included with multiple bracket options

Part of the Ranco A30 series, this temperature control is readily adaptable to nearly all commercial refrigeration applications. The pneumatic action provided by the vapor-filled capillary ensures accurate temperature sensing and switching. High-amperage contacts deliver reliable performance in demanding commercial environments. Installation instructions and adjustable mounting hardware are included for easy, fast installation with constant "Off" position available.
