The 70 kA Icu at 220/240 V AC and 50 kA Icu at 380/400 V AC mean it can safely interrupt fault currents up to those levels without upstream cascading. The TM-D trip gives fixed thermal and magnetic protection, so no field adjustment of the long-time pickup — it trips at 1 In (350 A) on overload.
Standards, approvals, and deployment context
Built and certified to EN 60947-2 and IEC 60947-2, so it meets the international standard for low-voltage switchgear and controlgear — the same standard that governs selectivity and coordination studies in industrial distribution. The IK07 impact rating confirms it survives a 2 J hammer blow (roughly a dropped tool) without cracking the case.
Dimensions and mechanical fit
The case measures 257 mm high × 150 mm wide × 108 mm deep. That 108 mm depth is the overall body dimension from mounting surface to the front of the toggle handle.
