Sparesadda 165 Litres RELAY OLP From To Suitable All Branded Single Door Refrigerator

Product Overview & Value Proposition

The Sparesadda Relay OLP is a specialized technical component designed specifically for the maintenance and repair of single-door refrigerators. Positioned as a critical electrical interface, this component serves as both a relay and an Overload Protector (OLP), ensuring that the compressor of a refrigeration unit operates within safe electrical parameters. This product is engineered for versatility, catering to a wide range of refrigerator capacities, specifically those ranging from 165 Litres to 400 Litres.

The primary value proposition of this Sparesadda component lies in its universal compatibility. It is marketed as being suitable for all branded single-door refrigerators, making it an essential spare part for technicians and DIY repair enthusiasts looking for a standardized solution to compressor startup and protection issues. By providing a reliable mechanism to manage the electrical load during the compressor's ignition phase, this relay helps prevent catastrophic motor failure due to electrical surges or overheating.

Targeting the aftermarket repair sector, this product is ideal for households and service centers that require a dependable, cost-effective way to restore functionality to single-door cooling units. Whether dealing with a minor startup failure or a need for preventative component replacement, the Sparesadda Relay OLP offers a streamlined solution for maintaining domestic refrigeration systems.

Core Specifications & Architecture

The technical architecture of the Sparesadda Relay OLP is built around precision electrical contact and standardized mounting. Understanding the internal and external metrics is crucial for ensuring correct installation and compatibility with existing refrigerator hardware.

Electrical and Contact Configuration

At the heart of this component is its electrical interface, designed to handle standard domestic power requirements. The device is rated for an operating voltage of 220-240 Volts, aligning with standard household electrical grids. The internal contact mechanism utilizes silver contact material, which is a critical specification for ensuring high conductivity and minimizing electrical resistance during the high-current draw periods typical of compressor startups.

The relay is configured with a 4-pin layout, providing the necessary connection points for the electrical circuit. The contact type is specified as normally open, meaning the circuit remains open until the appropriate electrical signal or condition is met, at which point the relay closes to allow current to flow to the compressor. The automatic operation mode ensures that the protection and switching functions occur without manual intervention, responding dynamically to the electrical state of the refrigerator.

Physical Dimensions and Build

The physical footprint of the Relay OLP is compact and standardized for easy integration into the compressor housing area. The technical dimensions are as follows:

• Item Height: 12 centimeters
• Item Width: 12 centimeters
• Product Dimensions: 12 x 12 x 12 cm
• Item Weight: 250 grams

The component utilizes a clamp connector type for secure electrical connections, reducing the risk of loose wiring which can lead to arcing or intermittent power supply to the compressor. For installation, it features a socket mount mounting type, allowing it to be seated firmly into the existing electrical socket assembly of the refrigerator's compressor unit.

Performance, Usability & Everyday Experience

In a real-world refrigeration environment, the performance of the Relay OLP is measured by its ability to facilitate smooth compressor starts and its efficacy in protecting the motor from electrical anomalies. Because this component is designed for single-door refrigerators with capacities between 165L and 400L, it is tuned to the specific torque and current requirements of compressors within that size class.

Operational Reliability

The use of silver contacts is a significant factor in the everyday user experience. In a refrigerator, the relay undergoes frequent cycling as the thermostat calls for cooling. Silver's ability to maintain low resistance helps in preventing the buildup of carbon deposits on the contacts, which is a common cause of relay failure. This ensures that the automatic operation mode remains consistent over time, providing the compressor with the necessary "kick" to start while immediately cutting power if an overload condition is detected.

Ease of Installation and Compatibility

From a usability standpoint, the 4-pin design and socket mount configuration simplify the replacement process. For a technician, the "Match and Buy" aspect of this product reduces the guesswork involved in sourcing parts. Since it is compatible with all branded refrigerators within the specified capacity range, it eliminates the need to search for brand-specific part numbers, which can often be difficult to locate in the aftermarket.

The Pack of 2 inclusion provides an added layer of utility, allowing for either a backup component to be kept on hand or for the simultaneous repair of two different units, enhancing the overall efficiency of a repair session.

Design, Build Quality & Efficiency

The design of the Sparesadda Relay OLP focuses on durability and electrical efficiency. While it is a small component, its build quality directly impacts the longevity of the entire refrigerator system.

Material Integrity

The choice of silver for the contact material is a deliberate engineering decision aimed at maximizing electrical efficiency. By reducing energy loss through heat at the contact points, the relay contributes to the overall energy efficiency of the refrigerator. The clamp connector type ensures that the physical connection between the wiring and the relay is robust, capable of withstanding the vibrations naturally produced by a running compressor.

Compact Form Factor

With a weight of 250g and a cubic dimension of 12 x 12 x 12 cm, the device is substantial enough to provide thermal mass for the OLP function while remaining compact enough to fit within the tight confines of a refrigerator's compressor compartment. The socket mount design ensures that once installed, the component is stable and does not shift, which is vital for maintaining the integrity of the 4-pin electrical connection.
