Motor protection breaker, magnetic-only trip
The MA trip responds only to short-circuit currents (magnetic protection), leaving overload protection to a separate thermal relay or motor starter — standard practice for motor branch circuits where the starter handles the thermal curve. Rated 12.5 A at 65 °C, it's sized for a motor full-load current in that range, not for general distribution. Breaking capacity is 36 kA Icu at 380/415 V AC, 50/60 Hz per IEC 60947-2. At 220/240 V it delivers 85 kA Icu; at 480 V UL-rated it holds 25 kA.
Mounts on a backplate (not DIN rail — the NSX frame uses a screw-fixed backplate mount). Three protected poles (3D), front connection both top and bottom. IP40 front face, IK07 impact resistance.
