What this MCCB delivers on the line
The 3VA2110-5KP32-0AE0: Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415 V, and still holds 75.6 kA at 500 V. At 690 V it drops to 3.7 kA — so on a 480 V or 600 V class panel this breaker clears high-fault scenarios without cascading upstream, but above 500 V verify the available fault current stays under that 3.7 kA knee. Three-pole, line-protection design, no undervoltage release or ground-fault module built in. Four auxiliary switches HQ are fitted as standard — that gives you status feedback back to the PLC without an add-on block.
Panel fit and thermal derating
Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — a standard MCCB footprint for DIN-rail or mounting-plate integration. The width is the critical number for multi-pole ganging in a distribution panel; at 105 mm per unit, three breakers side-by-side consume 315 mm of rail. Rated current holds flat at 100 A from 40 °C through 70 °C ambient — no derating needed across that range. That simplifies panel layout in warm enclosures or near other heat sources. Maximum power loss is 10 W. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. The storage limits govern handling and shipping — the breaker can sit in a cold warehouse or hot truck without damage.
Communication and auxiliary functions
This MCCB includes a communication function — it can report status and trip events to a higher-level system, which is useful for predictive maintenance or remote monitoring on a production line. No voltage trigger or trip indicator on the front face; the auxiliary switches handle the signaling. The supplied basic switch is order code 3VA21105KP320AA0 — that's the internal switching mechanism. For panel builders, that means the auxiliary switch design is 4 HQ switches, giving four independent signal paths for status feedback.
