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
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. That simplifies panel layout in warm enclosures or near other heat sources. Maximum power loss is 10 W.
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. For panel builders, that means the auxiliary switch design is 4 HQ switches, giving four independent signal paths for status feedback.
