FAQ

What is the adjustment range of the TM160D trip unit?
The TM160D trip unit has an adjustable thermal (overload) protection setting (Ir) ranging from 0.7 to 1 times the rated current. For this 160A unit, the adjustable range is from 112A to 160A. The magnetic (short-circuit) protection is fixed.

Can this circuit breaker be used in a DC system?
While the ComPact NSX series has models suitable for DC applications, this specific model, LV430630 with a TM-D trip unit, is primarily designed and rated for AC systems (50/60 Hz). For DC applications, you should consult the Schneider Electric catalog for a specifically rated DC model.

Is the breaking capacity (Icu) the same at all voltages?
No, the breaking capacity varies with the operating voltage (Ue). For the NSX160F model, the Icu is 85 kA at 220/240V AC, 36 kA at 380/415V AC, 35 kA at 440V AC, and 8 kA at 690V AC. Always verify the required breaking capacity for your specific installation voltage.
