ComPacT NSX 160H — 125 A thermal-magnetic, 3-pole
It is a 3-pole (3P) device, breaking capacity code H, delivering 100 kA Icu at 220/240 V AC, 70 kA at 380/415 V, and 65 kA at 440 V, all per IEC 60947-2. The frame is NSX160H, so the breaker accepts plug-in trip units and auxiliary modules through its 5 accessory slots.
At 415 V, the 70 kA Icu rating places this breaker in the H category — high enough for most distribution panels downstream of a transformer. For a 125 A feeder, the 10.78 W dissipation per pole stays manageable inside a standard IP40 enclosure.
The C16H3TM125C is listed as current production. No official successor has been issued — this remains the active order code for a 125 A TM-D in the NSX160H frame.
Front connections both upside and downside. Pitch between poles is 35 mm. IK07 impact resistance and IP40 front face handle typical enclosure environments.
