FAQ

Frequently Asked Questions

What does CB type mean?

CB-type denotes a specific compact changeover-switch construction popular in Asian and African distribution panels, distinct from larger industrial frames.

Is it automatic?

Auto and manual versions are both available. Auto versions integrate with a mains-failure sensing module.

Can I switch neutral too?

Yes – the 4P version switches all three phases plus neutral for complete isolation, which some installation codes require.

What certifications do you carry?

IEC 60947-6-1 type-test reports and CE documentation ship with every order.
