Superaircool, your reliable company within the HVAC industry. At Superaircool, we’re committed to providing cutting-edge solutions to enhance the efficiency of refrigeration units. Today, we’re thrilled to present our latest offering called our Universal Refrigerator PTC Start Solid State Relay. In this post, we’ll discuss the capabilities, benefits, and applications of this sophisticated relay created to improve effectiveness and reliability in refrigeration systems.

PTC relay, also known as contactless starter, is actually a PTC thermistor starter. When starting the compressor, you’ll find the PTC component temperature is low, the resistance is small, and it can be approximated as a straight-through circuit.

If the starting current increases to 4-6 times the normal, it will cause the temperature of the element to rise rapidly. Plus the resistance would increase to several orders of magnitude, and the passing current could become small, which may be regarded as an open circuit.

It suitable for compressors used in refrigerators, freezers, water coolers, de-humidifiers, vending machines and similar refrigeration applications. It plugs directly onto the compressor terminal pins, and is frequently used with the 4TM plug-on motor protector.

What exactly is what is a PTC Start Relay? What is its role within refrigeration equipment?

The PTC Start Relay, also called a Positive temperature coefficient Start Relay, is an essential component of refrigeration systems that initiates the compressor’s initial startup. It functions by utilizing the thermistor with a positive temperature coefficient that exhibits a swift increase in resistance when the temperature increases.

When the compressor is required to be started, its PTC thermistor gets heated because of the current flowing through it, which causes its resistance to rise dramatically. This increases the resistance and restricts the current flow to the compressor, thereby providing the initial boost required for the startup. When the compressor is operating, it will be able to cool down. PTC thermostat cools and allows normal operation to continue.

What is the difference between the Solid State Relay and traditional electromechanical relays?

Solid State Relays (SSRs) differ from conventional electromechanical relays regarding their design and operation. Although electromechanical relays use moving mechanical components such as contacts and switches to control electrical currents, SSRs employ semiconductor devices, like transistors or thyristors, to control switching. The solid-state design has several advantages, including higher switching speeds, greater performance, a longer life span, less electromagnetic interference, and more peaceful operation.
