Customer Cases

SSR
XSSR-JK

Custom SSR Terminal Solution for a North American Automation Equipment Manufacturer

Demand： A North American automation equipment manufacturer purchases solid state relays in large quantities for use in its industrial control equipment. In this application, two wires must be connected to each SSR terminal. During assembly, the customer found that the standard 10 mm square washer was smaller than the terminal opening. When the screw was tightened beyond approximately 2 Nm, the washer could rotate and push one of the wires out of position. For a manufacturer installing thousands of SSRs, this could lead to repeated adjustment, inconsistent wiring and additional assembly time.

Solution： After reviewing the customer's installation photo and technical feedback, XURUI identified the main cause:The 10 mm washer was not large enough to remain stable inside the terminal opening while securing two wires.XURUI therefore began developing a customized connection solution, including:•An enlarged 11.9 mm washer•A matching customized screw•A screw-head design that is easier to tighten consistently•Clearer recommended tightening torque informationThe larger washer is designed to provide better coverage inside the terminal opening, reduce rotation and prevent the wire from being pushed out during tightening.

Intelligent Monitoring Solid State Relay for Heating Systems: From Passive Switching to Active Fault Warning

Demand： An industrial equipment manufacturer operates heating systems that require high-power solid state relays to work continuously under high-temperature conditions.The customer originally used 100A solid state relays from a well-known brand. However, during long-term continuous operation, relay breakdown failures occurred repeatedly.

Solution： To address the monitoring limitations of conventional solid state relays, XURUI developed an intelligent monitoring solid state relay specifically for heating systems.This product has received a Chinese national invention patent. It has also passed the appraisal of provincial-level new product experts and was recognized as being at a leading domestic technical level.Unlike an ordinary solid state relay, the XURUI intelligent monitoring SSR combines power switching with real-time fault identification.It can monitor conditions including:•Solid state relay breakdown or abnormal conduction •Heater or heating element open circuit •Load failure •Abnormal circuit conditions •Other heating-system operating faultsWhen an abnormal condition is detected, the relay immediately outputs an alarm signal, allowing the control system to respond before the fault causes greater damage.

Frequently Asked Questions

Summarize high-frequency questions, quickly solve puzzles, and help efficient selection and use.

How can I get an accurate quotation?

Please provide the product model or drawing, application, voltage and current, actuator or terminal configuration, cable requirements, expected quantity, destination market and required certifications. The more complete the information, the faster we can recommend a suitable solution and prepare an accurate quotation.
What is not covered by the warranty?

The warranty does not cover damage caused by incorrect wiring, excessive electrical load, improper installation, unauthorized modification, misuse, normal wear or operation outside the product’s specified environmental conditions. Final warranty coverage is subject to the applicable product specification and sales agreement.
What does the product warranty cover?

The warranty covers verified defects in materials or manufacturing under the specified operating and installation conditions. Depending on the case, XURUI may provide technical analysis, replacement parts, repair or product replacement in accordance with the agreed warranty terms.
What is your standard production lead time?

Lead time depends on product type, order quantity, material availability and customization requirements. Standard products generally have shorter lead times, while customized products require additional time for approval, tooling or validation. The confirmed delivery schedule will be stated in the quotation.
Which certifications and compliance documents are available?

Certifications vary by product series and target market. Applicable certificates, test reports and material compliance documents can be provided for qualified models. Please confirm the exact product number and destination market before requesting documentation.
Can you support samples and small trial orders?

Yes. We support sample orders and small trial orders for most standard products. The minimum order quantity depends on the product series, specifications and packaging requirements. Please send us the part number or application details for confirmation.
What customization services do you offer?

We provide OEM and ODM support, including actuator structures, terminals, cables, connectors, electrical ratings, housing colors, labels and packaging. Each request is reviewed for technical feasibility, tooling requirements, testing and expected order volume.
How long does custom sample development take?

Sample lead time depends on the level of customization. Changes ivolving existing components are generally faster, while new molds, special materials or additional validation require more time. A confirmed schedule will be provided after reviewing your drawings and specifications.
How are custom sample costs calculated?

Sample costs may include materials, tooling, engineering, testing and certification-related expenses. We provide a detailed quotation before development begins. Any arrangement for refunding or crediting sample fees will be stated clearly in the quotation.
How do you ensure product traceability?

Key materials, production batches, assembly records and test results are controlled through lot identification. This allows us to trace products back to relevant materials, production dates and inspection records when required.
What quality inspections are performed?

Our quality process includes incoming material inspection, in-process control, functional testing and final inspection. Product-specific checks may include operating force and travel, contact resistance, insulation resistance, dielectric strength, sealing performance, temperature rise and endurance validation.
