What the 30 kA at 400 V means for your panel
At 220–240 V AC that figure rises to 50 kA Icu, and at 110–130 V AC it reaches 100 kA Icu, all certified to IEC 60947-2. For DC circuits it delivers 10 kA Icu at 125 V DC (1-pole) or 250 V DC (2-pole). That spread covers most distribution panels in light industrial and commercial buildings where the transformer impedance keeps prospective fault current under 30 kA.
Integration — panel fit and connection
The breaker mounts to a backplate (fixed mounting, not DIN rail) with a 25 mm connection pitch. Both line and load connections are front-accessed, so it panels into a standard distribution board without rear-bus adaptors. Dimensions are 100 mm wide × 130 mm high × 60 mm deep — a 4-pole MCCB that fits a 100 mm module slot.
Trip unit and protection — what the TM-D does
Mechanical durability is rated at 13,000 cycles — typical for a distribution MCCB that sees infrequent switching.
