Frequently Asked Questions

Q1: What standards does your low voltage switchgear comply with?

Our switchgear is designed and manufactured in full compliance with the international IEC 61439 series of standards (specifically IEC 61439-1 & -2). We also hold complete Type Test Certification (TTA) from independent, accredited laboratories.

Q2: What is the meaning of "Form 4B" separation?

Form 4B is a classification per IEC 61439 that specifies the highest degree of internal separation. It ensures complete isolation between busbars, functional units, and outgoing terminal compartments, enhancing safety and allowing for safer maintenance.

Q3: What is the advantage of a withdrawable circuit breaker design?

A withdrawable design allows the circuit breaker to be disconnected, isolated, and moved to a "test" or "withdrawn" position without de-energizing the entire panel, significantly minimizing downtime for maintenance.

Q4: What is the short-circuit withstand rating (Icw) of your panels?

Our standard panels are rated for a short-time withstand current (Icw) of 50kA for 1 second. Higher ratings can be engineered for specific projects depending on requirements.

Q5: What is the typical delivery lead time for a custom switchgear project?

For standard configurations, the lead time is typically 4-6 weeks. For fully customized projects involving complex engineering, the lead time can range from 8 to 12 weeks.

Q6: What certifications do your electrical products hold?

Our company holds ISO 9001 Quality Management System certification and international product approvals including CE, CB, UL, ETL, and CCC to ensure global quality standards.
