Distribution cabinet UL certification-UL67, UL891, UL508

• switchboard (UL 67): A switchboard is a device used to distribute electrical energy, and its safety is essential to the operation of the entire power system. UL 67 specifies and tests the structural, performance and safety characteristics of switchboards to ensure safe and stable operation under various conditions.

• switchgear (UL 891): A switchgear is a device used to control, protect and monitor electrical systems. The UL 891 standard specifies and tests the design, construction, performance and safety characteristics of switchgear to ensure that it can operate safely and reliably under high voltage and high current conditions.

• switchgear (UL 1558): Armored low-voltage circuit breakers and switchgear are equipment used in power distribution systems that can automatically cut off the power supply under abnormal conditions such as overload, short circuit or undervoltage to protect circuits And equipment safety. UL 1558 standards specify and test the design, construction, performance and safety features of armored low-voltage circuit breakers and switchgear.

• Motor Control Center (UL 845): A motor control center is a device that integrates various motor control equipment and protection equipment to control, monitor and protect the motor. UL 845 standards specify and test the design, construction, performance and safety features of motor control centers.

Distribution cabinet UL certification process includes the following steps:

1. to submit the application: enterprises need to fill in the UL application form, provide specifications, enterprise standards, instructions, technical drawings and other information, and then send samples to Ankejie.

2. Cost Quotation: Arcoxa determines the test plan and cost based on the information provided.

3. to the public payment: after the applicant confirms the quotation, sign the application form and service agreement and pay the project fee.

4. type test: Ankejie tests the applied products according to UL standards. For special products, Ankejie needs to interface with UL certification center.

5. test report: If the product passes the test, Ancogen will provide the test report.

6. factory inspection: Ankejie inspects and reviews the product production plant of the applicant enterprise.

7. issued a certificate: after the audit, officially authorized to use UL mark.

In addition, the UL508A evaluation of the power distribution cabinet begins with the evaluation of the structural design and electrical wiring of the electrical control cabinet, including general requirements, enclosure requirements, power lines and control circuit requirements. The selection of components needs to meet the requirements of UL508A, and finally the verification of claims and marks. Quality control in the manufacturing process to ensure compliance with UL508A standards.
