As a leading high-tech manufacturer and wholesale supplier based in China, ATO Relays brings over 15 years of industry experience to the global electrical components market. With thousands of standard models and more than 30 specialized series, ATO supplies factory-direct relay technologies engineered for safety, durability, and cost efficiency. Through comprehensive OEM/ODM services, ATO assists clients in developing custom current, voltage, and structural specifications from initial layout to delivery.

ATO’s electromagnetic series offers diverse configuration options for broad circuit conversion tasks. Available in DPDT, 3PDT, and 4PDT variants with coil voltages ranging from 12V DC up to 240V AC, these electromechanical switches utilize silver-alloy contacts for superior conductivity and heat dissipation. The lineup also features high-density SPDT DIN rail mounted slim relays operating on 24V DC coils—ideal for space-constrained PLC interface cabinets—as well as multi-channel relay modules designed to streamline control wiring.

For high-duty cycle applications, ATO provides a comprehensive selection of contactless Solid State Relays (SSRs). The offering spans single-phase and 3-phase models (DC-AC and AC-AC) supporting load currents from 10A to 120A, alongside high-amperage industrial SSRs rated at 60A, 80A, 100A, and 350A. Featuring microelectronic isolation and optional DIN rail heat sink assemblies, ATO’s SSRs deliver fast switching speeds, strong anti-interference performance, and spark-free operation.

Backed by millions of units in stock for same-day dispatch, ATO guarantees reliable lead times and predictable supply chain performance. ATO Relays actively serves commercial buyers, panel builders, and automation distributors across North America, Europe, Australia, and Southeast Asia, making professional-grade electrical switching accessible worldwide.
