Frequently Asked Questions

What is the breaking capacity of the C25F32D250 NSX250F?

The NSX250F provides an ultimate breaking capacity (Icu) of 36 kA at 415V AC, meeting the requirements of IEC 60947-2 for industrial-grade short-circuit protection.

Is the NSX250F suitable for three-phase systems?

Yes. The C25F32D250 is a 3-pole device rated at 415V AC, making it directly suitable for three-phase 400/415V TN and TT distribution systems.

What trip technology does the NSX250F use?

The NSX250F series uses thermal magnetic trip technology, providing both overload (thermal) and short-circuit (magnetic) protection without requiring an external power supply.

Can accessories be added to this circuit breaker?

The ComPacT NSX new generation platform supports a wide range of accessories including auxiliary contacts, shunt trips, under-voltage releases, and rotary handles — consult the NSX series accessory catalogue for compatibility.
