Breaking capacity is 40 kA Icu at 220/240 V AC and 25 kA Icu at 380/400 V AC, both conforming to EN/IEC 60947-2. At 440 V AC it still holds 20 kA Icu, so it handles moderate fault levels across common low-voltage networks. The fixed TM-D trip has a long-time pickup fixed at 1 In and a fixed long-time delay, meaning the thermal curve is preset — no field adjustment for overload pickup. This suits distribution boards where the load is known and stable.
Mounts fixed to a backplate with a 35 mm connection pitch. The toggle handle gives clear visual indication of the contact position. IP40 enclosure protection and IK07 impact resistance make it suitable for general-purpose indoor panels where occasional tool drops or dust ingress are a concern.
