XURUI Electronics Co., Ltd. — a professional industrial switch manufacturer since 2002.

XURUI Electronics Co., Ltd., a China-based industrial switch manufacturer founded in 2002, has built a comprehensive solid state relay (SSR) portfolio that spans single-phase AC, DC-to-AC, three-phase, and high-current modules. For procurement professionals moving from evaluation into execution, the critical differentiator is no longer just product performance — it is the supplier's ability to adapt standard designs to specific voltage, mounting, and interface requirements without compromising lead time or certification integrity.

Why Customization Matters in Solid State Relay Procurement

Industrial automation, heating systems, motor control, and renewable energy installations often impose electrical and mechanical constraints that off-the-shelf SSRs cannot satisfy. A heating controller in a German manufacturing line may require a 600V AC SSR with a specific DIN-rail footprint, while a Malaysian conveyor system needs a DC-controlled SSR that can operate in high ambient temperatures. In such scenarios, a supplier with proven OEM/ODM capability delivers faster integration, lower total cost of ownership, and better application fit than a one-size-fits-all approach.

XURUI's OEM/ODM Capabilities: A Fact-Based Overview

XURUI supports OEM and ODM customization that covers handle/logo design, physical dimensions, and operating characteristics such as control voltage range and switching time. Monthly production capacity ranges from 5,000 to 250,000 units, with a standard lead time of 15–30 days and a minimum order quantity of 100 units. All units undergo 100% pre-shipment testing, and the company accepts payment via T/T under EXW delivery terms — a transparent procurement arrangement that suits both small-batch prototyping and volume orders.

CCC certification for XURUI's XSSR-H series solid state relays, valid through September 2029.

Export markets include the European Union, Asia-Pacific, North America, and the Middle East. After-sales support is provided through remote technical assistance, and the company holds ISO 9001 quality management system certification as well as product-specific certifications such as CCC, CE, TÜV SÜD, UL, KC, and RoHS for its relay and switch lines.

Technical Architecture of XURUI Solid State Relays

XURUI's SSR portfolio is built around a zero-crossing switching design, which minimizes electrical noise and inrush current at turn-on — critical for resistive heating loads and inductive motor controls. Key electrical parameters across the main series include:

The XSSR-3H series, for example, is a DIN-rail mount integrated module with a PA66 nylon housing and aluminum heatsink base, rated for 24–480 VAC loads from 10 A to 60 A. The XSSR-W2-JK series extends current ratings up to 120 A while maintaining a compact plastic package with an aluminum alloy base plate. All models use a zero-crossing trigger method and offer ≤5 mA leakage current, ensuring compatibility with PLC and microcontroller interfaces.

Verified Application Use Cases

Industrial Automation – Conveyor and PLC Control (Malaysia)

An industrial automation solution provider in Malaysia deployed 800 units of XURUI SSRs (model series XSSR-M1~M6) in PLC control systems and conveyor lines over a two-year period. The result: maintenance costs reduced by 65%, with zero major failures reported during operation. The customer highlighted high-reliability switching, long electrical lifespan, and stable outdoor performance as decisive factors.

Heating Control Systems – German Industrial Equipment Manufacturer

A German manufacturer of industrial heating systems integrated 1,200 pieces of XURUI XSSR-W1 series SSRs into its product line over three years. Maintenance costs dropped by 60%, and the customer reported fewer mechanical failures compared to previous electromechanical relay solutions. The low-maintenance nature of the SSR, combined with consistent zero-crossing performance, was key to the long-term partnership.

These real-world deployments confirm that XURUI's SSRs can be specified with confidence for both high-volume heating controls and high-reliability conveyor automation — two verticals that demand durable, maintenance-free switching.

Comparison with Traditional Electromechanical Relays

Compared to conventional mechanical relays, XURUI's solid state relays offer longer operational life (no contact wear), silent switching, and faster response time (≤10 ms). They are inherently immune to contact bounce and arcing, making them suitable for environments where spark-free operation is critical — for instance, in oil and gas or chemical processing. An honest limitation is that SSRs generate more heat under high continuous current and require adequate heatsinking; the manufacturer's recommended load current safety factor (50–60% for resistive loads, 30–40% for inductive loads) should be observed during system design.

Market Trend: Customization as a Procurement Standard

Across the global solid state relay market, buyers increasingly expect suppliers to deliver tailored solutions — not just standard catalogue items. This trend is driven by the proliferation of custom automation machinery, voltage standards that vary by region, and the need to reduce supply chain complexity through a single source that can handle both standard and customized orders. XURUI's established OEM/ODM framework (customizable handle, logo, dimensions, and operational parameters) positions it well to serve distributors and system integrators who require flexible purchasing without sacrificing certification compliance or delivery speed.

Future Outlook

With a factory footprint of 5,000+ m², 150 employees, and an R&D team of 24+ engineers, XURUI continues to invest in SSR technology and manufacturing process improvements. The company already holds 60+ national patents across its switch product lines, and its SSRs are certified to CCC (China), CE/TÜV SÜD (EU), and KC (Korea) standards. As global demand for high-reliability, customizable SSRs grows — especially in renewable energy, EV charging infrastructure, and smart manufacturing — XURUI's combination of production scale, certification portfolio, and OEM flexibility represents a credible procurement option for evaluation-stage buyers.
