FAQs
Can I use this breaker for DC applications?
Yes, this model supports DC applications up to 72V.
What does the 1+N pole configuration mean?
It means the breaker protects and switches one live phase while also switching the neutral wire simultaneously.
Is this breaker suitable for outdoor installation?
No, the device has an IP20 rating and must be installed within a protective, moisture-proof enclosure.
What is the trip curve of this model?
This model features a Type C trip curve, which is standard for handling moderate inductive startup surges.
Does this breaker contain hazardous materials?
No, the device is manufactured without the use of halogens or silicones.
What is the maximum breaking capacity?
The rated breaking capacity is 6000 A.
Troubleshooting
Breaker trips immediately upon switching on
Identify if there is a short circuit in the downstream wiring or if the connected load exceeds the 16A capacity.
Breaker lever is loose or won't stay in the ON position
Verify there is no active fault or short circuit on the line. If the fault persists with no load, replace the unit.
