What this 225 A MCCB delivers in a panel
The 100 kA Icu at 220–240 V AC (IEC 60947-2) means it clears a bolted fault at that level without rupturing — that is the headline interrupting rating for most North American 240 V distribution. At 380–415 V AC it still holds 36 kA Icu, and at 440 V AC it delivers 25 kA Icu, so the same breaker works across a 50/60 Hz three-phase network without swapping frame sizes. This unit includes integral earth-leakage protection alongside overload and short-circuit protection — one device covers ground-fault and overcurrent, which saves a panel row versus a separate ELCB downstream. The TM-D trip curve is thermal-magnetic, so it handles motor inrush without nuisance tripping on the thermal element while the magnetic coil clears hard shorts fast.
Mounting and integration into a distribution board
Fixed backplate mount with front-front connections — both line and load terminate on the front face, so the breaker can be wired into a panel without rear-access busbars. IP20 finger-safe protection on the front cover, IK07 impact resistance per EN 50102. Toggle control with positive contact indication — the handle position mechanically confirms the contact state, no ambiguity when the breaker is tripped.
