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 (specifically IEC 61439-1 & -2). We hold complete Type Test Certification (TTA) from independent, accredited laboratories to validate performance and safety.

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

Form 4B per IEC 61439 specifies the highest degree of internal separation. It ensures complete isolation between busbars, functional units, and outgoing terminal compartments, enhancing safety by containing potential internal fault arcs and allowing safer maintenance.

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

A withdrawable design allows circuit breakers to be disconnected and moved to a "test" or "withdrawn" position without de-energizing the entire panel. This enables rapid maintenance or replacement, significantly minimizing downtime for critical systems.

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. This means the assembly can withstand thermal and electromagnetic stresses of a major fault while allowing upstream protection to clear the fault safely.

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 depending on technical specifications.

Q6: Are higher protection grades available for harsh environments?

Yes, while our standard indoor degree of protection is IP54, we can provide customized solutions up to IP65 to meet the requirements of more demanding environmental conditions.
