AC contactor relays are essential components in electrical circuits, especially for starting and stopping high-power equipment like compressors and fans. At Suzhou Eletek, we specialize in manufacturing AC contactor relays that offer exceptional switching capabilities, ensuring smooth and safe operation of your appliances. Our relays are designed to handle high inductive loads with minimal arcing, thanks to advanced arc quenching technology. The contacts are made of silver-cadmium oxide or silver-tin oxide, providing low contact resistance and high resistance to wear. This results in a relay that can operate reliably for tens of thousands of cycles without performance degradation. Our AC contactor relays are available in various sizes, from compact models for small refrigeration units to larger ones for industrial HVAC systems. Each relay is rigorously tested for insulation resistance, dielectric strength, and thermal stability to ensure it meets the highest quality standards.

Frequently Questions

What is the difference between an AC contactor and a relay?

An AC contactor is a type of relay specifically designed for handling high electrical loads, typically above 10 amps, and is often used in industrial and HVAC applications. It features heavy-duty contacts capable of switching large currents and voltages, and it is constructed to withstand high inrush currents. A standard relay, on the other hand, is generally for low-power signal switching, such as in control circuits. Our AC contactor relays are built with robust materials and arc suppression to safely interrupt high-power circuits, making them suitable for motor starts and compressor controls. They also have a longer mechanical and electrical life compared to general-purpose relays.
To select the correct AC contactor relay, you need to consider the following factors: coil voltage (must match your control supply), contact current rating (should be at least 1.5 times the full-load current of the device you control), contact voltage rating, and the number of poles (single or three-phase). Additionally, assess the environment: temperature range, humidity, and whether the relay will be exposed to dust or chemicals, which may require an enclosed version. It’s also vital to consider the duty cycle – how frequently the relay will operate. For frequent switching, choose a relay with a higher mechanical endurance. Our technical team can assist you in selecting the appropriate model and even customizing the relay to fit your exact specifications.
Our AC contactor relays are certified to meet international safety and quality standards, including UL (Underwriters Laboratories), CE (Conformité Européenne), and RoHS (Restriction of Hazardous Substances). We also obtain CCC (China Compulsory Certification) when required for the Chinese market. These certifications ensure that our relays are safe, reliable, and environmentally friendly. Additionally, our manufacturing processes are ISO 9001:2015 certified, guaranteeing consistent quality control from raw materials to final assembly. If you have specific certification requirements, please let us know, and we can discuss further compliance needs.
Absolutely. Suzhou Eletek has an experienced engineering team that can customize AC contactor relays according to your branding, design, or functional specifications. We offer various customization options, including: – Coil voltage (e.g., 12V, 24V, 110V, 220V) – Contact material and ratings – Mounting dimensions and terminal connections – Enclosure type (e.g., open, dust-proof, waterproof) – Custom packaging and labeling. We also welcome samples for testing and can provide technical documentation and test reports. Our OEM customers benefit from our cost-effective production without compromising on quality, ensuring your brand is associated with reliability.
For stock models of AC contactor relays, our MOQ is only 100 pieces, which is suitable for small startups and trials. For customized products, the typical MOQ is 500 to 1,000 pieces, depending on the complexity of the customizations. However, we aim to be flexible and understand that each client has unique needs. We offer generous quantity discounts and a sample order policy, so you can test the product before making a large purchase. Our sales team will be happy to provide you with a tailored quote based on your requirements.

Advanced Arc Suppression Technology for Enhanced Safety

Advanced Arc Suppression Technology for Enhanced Safety

Suzhou Eletek’s AC contactor relays incorporate cutting-edge arc suppression techniques, such as magnetic blow-out and arc chutes, which ensure safe interruption of high current circuits. This technology reduces contact wear and prevents the formation of harmful arcs that could damage the relay or surrounding components. As a result, our relays have a longer electrical life and maintain consistent performance even after thousands of switching cycles. This feature is particularly crucial in applications with frequent motor starts, where ordinary relays may fail prematurely. Choose our AC contactor relays for superior safety and durability.
Extensive Testing and Quality Assurance

Extensive Testing and Quality Assurance

Every AC contactor relay leaving our factory undergoes a series of stringent tests to ensure it meets international standards. We conduct routine checks on coil resistance, contact resistance, dielectric strength, insulation resistance, and operational voltage range. Our relays are also subjected to accelerated life testing, simulating real-world conditions to verify their endurance. With our commitment to quality, we provide a 12-month warranty and full traceability via batch numbers. This dedication to excellence has earned us certifications from UL and CE, giving customers worldwide confidence in the reliability of our products.
