Can it protect both motors and general power distribution?

Yes, its adjustable LSI trip unit allows settings tailored to motor starting characteristics, making it suitable for both general distribution and motor protection.

What is the LSI protection feature?

LSI stands for Long-time, Short-time, and Instantaneous protection, offering multi-stage overcurrent detection to minimize unnecessary shutdowns and optimize system protection.

How does the mechanical lockout enhance safety?

It prevents unauthorized operation or accidental switching, ensuring the breaker remains in its intended state (e.g., OFF during maintenance) for added physical security.

Where can I find technical documentation?

Detailed manuals and specifications are available on the official Siemens Industry Online Support (SIOS) portal by searching for the product model.

What are the typical operating conditions?

It is designed for enclosed areas not exposed to severe dust, corrosive vapors, or damaging gases, adhering to permissible ambient temperatures.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier providing 3D software design, ODM, industrial automation, product sales, installation, commissioning, maintenance, and repair services. It supports extensive customization and has documented finished-product inspection instructions, quality assurance, and stated lead times within 15 working days in both peak and off-peak seasons. However, it has no overseas showrooms, agents, branches, or offline trade-show experience, and no new products were developed in the past year. Supplier-management, corrective-action, and complaint-handling procedures exist but lack written records. Certification is listed as NIL, quality-control staffing is below five, and R&D engineer experience totals two years. Export activity is established, with 31%–40% of sales from exports and three years of export experience. Evidence of specific customer cases is not provided.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and provides industrial automation-related one-stop services, including product sales, solutions, installation and commissioning, maintenance, and repair. Its stated focus covers cement, packaging, printing, rubber, textile, and machine-tool industries.

CertificationsSupplier management system certification is explicitly recorded as NIL. The provided information therefore does not demonstrate possession of relevant certifications.

After-Sales capabilityThe supplier states that it provides installation, commissioning, maintenance, and repair services and has a quality-assurance system. However, it has no overseas showroom, agent, or branch, and its complaint-handling procedure has no written records, limiting evidence of formalized after-sales execution.

Production capacityThe supplier reports lead times within 15 working days during both peak and off-peak periods, maintains written and uniformly followed finished-product inspection instructions, and lists annual production output above the stated threshold. Nevertheless, quality-control staffing is below five and the service-capability assessment procedure has no records.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same capability is confirmed in two slices, providing direct evidence of broad customization coverage.

Product Q&A

Q:What is the primary function of this MCCB?

It provides reliable protection against overcurrents and short circuits, acting as an automatic safety device to prevent equipment damage and ensure personnel safety.

Q:What is the rated breaking capacity (Icu)?

The rated breaking capacity is 55kA at 500V AC, allowing it to safely interrupt severe short-circuit currents without sustaining damage.

Q:Can it be used in harsh industrial environments?

It is climate-proof for enclosed areas. For severe conditions like high dust or corrosive vapors, it must be installed in appropriate protective enclosures.

Q:What are the advantages of the withdrawable version?

It allows safe isolation and removal from live busbars without de-energizing the system, reducing downtime and enhancing maintenance safety.

Q:Is it compatible with non-Siemens panels?

While possible, it is recommended to use Siemens breakers in Siemens panels for optimal performance. Verify voltage, current, and dimensions match your system requirements.
