The Importance of Compressor Relays

Compressor relays are critical components that control the starting circuit of single-phase compressors. Most single-phase compressors require a start capacitor and a start relay to provide additional starting torque. The relay engages the start capacitor during compressor startup and disengages it once the compressor reaches approximately 75% of full operating speed.

A faulty compressor relay can cause a range of problems including compressor failure to start, humming compressor, tripping overload protector, burnt start windings, and complete compressor failure. In Oman’s extreme climate where AC systems operate under high load conditions, properly functioning compressor relays are essential for reliable compressor operation.

Our inventory includes various relay types, amperage ratings, and configurations to suit every requirement. For other compressor components, explore our selection of compressor overload protectors, start capacitors, and run capacitors.

1. Current Relays (Magnetic Relays)

Current relays are the most common type of compressor start relay used in smaller residential AC and refrigeration compressors. They operate based on the electrical current drawn by the compressor’s run winding. When the compressor starts, high inrush current energizes the relay coil, closing the contacts and engaging the start capacitor.

Specifications: Available for compressors from 1/8 HP to 3 HP. Amperage ratings from 5A to 30A. Voltage ratings include 115V, 230V, and universal. Features include normally open contacts, solenoid-operated switching, and plug-in or screw terminal connections.

Applications: Small hermetic compressors in residential refrigerators, freezers, window ACs, and small split ACs.

Popular models include: 3-in-1 current relay for refrigerator compressors, universal current relay for 1/4 HP to 1/2 HP compressors, heavy-duty current relay for 1 HP to 2 HP compressors.

2. Potential Relays (Voltage Relays)

Potential relays operate based on the back electromotive force (EMF) voltage generated by the compressor’s start winding. When the compressor reaches approximately 75% of full speed, the back EMF voltage rises, energizing the relay coil and opening the contacts to disengage the start capacitor. These are commonly used in larger residential and commercial compressors.

Specifications: Available for compressors from 1/2 HP to 5 HP and above. Pick-up voltage ratings from 140V to 400V. Drop-out voltage ratings from 40V to 140V. Features include normally closed contacts, precise voltage sensing, and robust construction.

Applications: Residential split AC compressors, commercial refrigeration compressors, heat pump compressors, and larger hermetic compressors.

Popular models include: Copeland potential relay, universal potential relay with adjustable pick-up voltage, potential relay for 1-3 HP compressors, and heavy-duty potential relay for 3-5 HP compressors.

3. PTC Relays (Positive Temperature Coefficient Relays)

PTC relays use a thermistor that increases resistance dramatically when heated. During startup, the PTC element has low resistance, allowing current to flow to the start winding. As the PTC element heats up, resistance increases, effectively disconnecting the start winding. PTC relays have no moving parts, making them highly reliable.

Specifications: Available for compressors from 1/8 HP to 1 HP. Voltage ratings include 115V and 230V. Features include solid-state construction, no moving parts, silent operation, and automatic reset capability.

Applications: Small hermetic compressors, refrigerators, freezers, dehumidifiers, and small window ACs.

Popular models include: PTC relay for refrigerator compressors, universal PTC starter, and PTC relay with built-in overload protection.

4. Solid-State Compressor Relays

Solid-state relays use electronic components to control compressor starting. They offer precise timing, adjustable parameters, and enhanced reliability compared to electromechanical relays.

Specifications: Available for compressors from 1/4 HP to 5 HP. Features include microprocessor control, adjustable start time, LED status indicators, and built-in diagnostics.

Applications: Commercial refrigeration, precision cooling systems, and applications requiring advanced starting control.
