SST120 Application Field and Working Principle

The SST120 series thermal protection device, created by PlumbTech Industries, is a highly reliable safety device for temperature control purposes. It is often used in industrial equipment such as HVAC, cooling systems, refrigeration systems, and other industries that require temperature control. It is a must-have for any facility that is serious about protecting their assets from damage caused by high temperatures.

The SST120 is designed to provide thermal protection for equipment when the temperature exceeds a specified limit. This is accomplished by using a mercury filled capsule enclosed in a steel housing. When the preset temperature is exceeded, the capsule expands, pushing against the spring-loaded diaphragm, which acts to open the switch contacts, thus de-energizing the protected load.

The SST120 feature several benefits, namely an accurate temperature reading, adjustable set points, enhanced switching reliability, and ease of installation. The device is rated for a maximum operating temperature of 120°C with an adjustable set point range from 20°C to 90°C. This allows for flexible temperature settings and application versatility. It also uses gold-plated contacts for superior reliability and electrical performance.

The SST120 series is also designed for ease of installation. It comes pre-wired and includes an optional cable and mounting hardware for mounting the product to the equipment. This makes it ideal for situations where space is limited and mounting is difficult. Other features include a highly visible red-over-green indicator light, an adjustable bimetal element, and an adjustable turn-on delay for specific applications.

In addition to the SST120, PlumbTech also offers a similarly designed SST122 series thermal protection device. This device is rated for a maximum operating temperature of 250°C and includes an adjustable set point range from 40°C to 140°C. Like the SST120, it also includes gold-plated contacts, pre-wired installation, and adjustable bimetal elements. The SST122 is ideal for protection of larger installations or applications requiring faster response times.

The SST120 and SST122 are both excellent options for temperature overheat safety protection. They are highly reliable, easy to install, and feature a wide range of adjustable temperatures.
