Square D Model 85 Life Gard Temperature Control Switch

The Square D Model 85 Life Gard Temperature Control Switch is a temperature control device designed for use in various industrial, commercial, and residential applications. It helps maintain a specified temperature range by controlling the operation of heating or cooling systems. Below is a detailed product description:

Key Features:

• Model: 85 Life Gard
• Type: Temperature Control Switch (often referred to as a thermostat or temperature limit switch)
• Temperature Range: Typically adjustable to operate within a specific temperature range (e.g., 50°F to 180°F, or similar depending on the model) but can vary. The range is designed to allow precise control of temperatures in heating or cooling applications.
• Design: The Life Gard model is built with a high-quality bimetallic element that senses temperature changes. It’s designed to cut off or cycle equipment to maintain or limit temperatures for safety or efficiency.
• Switching Action: The device has a single-pole, double-throw (SPDT) or double-pole, double-throw (DPDT) switch design, depending on the model, allowing it to control multiple devices or systems.
• Enclosure: It typically comes with a dust-tight and moisture-resistant enclosure that can be used in harsh environments.
• Safety Features: The Life Gard series is specifically designed with safety in mind, ensuring over-temperature protection to prevent damage to systems like motors, heating elements, or compressors.
• Reset Function: Many of these models include an automatic or manual reset mechanism to restore functionality once the temperature returns to the normal operating range.

Applications:

The Square D Model 85 Life Gard Temperature Control Switch is commonly used in various industries and applications, such as:

• HVAC Systems: Ensures the temperature remains within a safe and efficient range, protecting heating or cooling units from overheating.
• Industrial Equipment: Protects machines and equipment from excessive heat that could cause damage or operational failure.
• Motors & Compressors: Used in temperature protection systems to prevent overheating of motors or compressors.
• Appliances: Applied in domestic or commercial heating appliances, including water heaters, industrial ovens, and other heat-driven systems.
• Electrical Panels: Can be used to monitor and control temperature-sensitive components in electrical control panels and systems.

Design Considerations:

• Adjustability: The temperature setting can be adjusted to meet the specific needs of the application.
• Contact Ratings: The control switch can be rated for different voltages and current levels (e.g., 120V, 240V, or higher), depending on the equipment it’s controlling.
• Mounting: Typically features an easy-to-install mounting bracket, making it versatile for a wide range of applications.

Benefits:

• Protective Function: Provides over-temperature protection, reducing the risk of damage to sensitive equipment due to heat buildup.
• Energy Efficiency: Helps maintain an optimal operating temperature range, improving system efficiency and potentially reducing energy consumption.
• Reliability: Square D is known for manufacturing durable and long-lasting electrical components, and the Model 85 Life Gard switch is no exception, providing reliable temperature control for years of service.
