Information About L480B

The Honeywell L480B is a low-limit mechanical temperature controller designed for use in air conditioning and refrigeration systems to prevent coil freeze-up or ensure temperature safety in cooling environments. Commonly referred to as a "freezestat," it monitors air or surface temperature and automatically resets if temperature conditions return to safe levels. It features a 20-foot capillary sensing element and is built for dependable operation in applications such as display cases, beverage coolers, freezer cabinets, and walk-in units. The L480B is widely used in commercial refrigeration and agricultural frost protection.

Key Features:

  • Application-Specific Design: Ideal for refrigerated enclosures, air handlers, and frost monitoring systems.
  • Temperature Range: Adjustable setpoint from 20°F to 60°F (–6.7°C to 15.6°C).
  • Fixed Differential: 10°F (5.6°C) differential provides consistent performance and reset behavior.
  • Capillary Sensing Element: Includes a 20-foot (6.1 m) capillary tube for remote sensing.
  • Switch Type: SPDT (Single Pole, Double Throw) switch with automatic reset for reliable temperature control.
  • Rugged Construction: Enclosed dustproof and moisture-resistant switch housing enhances durability.
  • Mounting Flexibility: Can be mounted horizontally or vertically for versatile installation.
  • Voltage Compatibility: Rated for 120/240 VAC operation.
  • Certifications: UL Listed and CSA Certified for safety compliance.
  • Weight: Approximately 1.6 lbs (0.73 kg)

The L480B offers reliable and simple protection against low-temperature damage in refrigeration and HVAC systems. With its extended sensing capability and durable design, it is a trusted solution for maintaining temperature stability in both commercial and agricultural environments.
