Siemens 3VA2116-5KP42-0AA0 — 160 A SENTRON MCCB with ETU850 Trip Unit
Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 690 V figure is low enough that you need to verify coordination if that's your service voltage; at typical 400/415 V distribution levels the 121 kA SCCR covers most utility-fault scenarios without cascading upstream. That means no de-rate calculation for a warm panel — the breaker delivers its full nameplate at any temperature inside its operating range of -25 °C to 70 °C.
Compliance documentation is standard for Siemens SENTRON: the breaker is designed to meet IEC 60947-2 and UL 489 requirements. RoHS and REACH declarations of conformity are available on request.
Integration & Physical Fit
Verify the busbar or cable-entry clearance against the 86 mm depth; it fits most distribution boards without a deep enclosure. The ETU850 trip unit includes a communication function, enabling integration with higher-level monitoring or energy-management systems. No undervoltage release or voltage trigger is fitted as standard; those are field-addable accessories if your safety circuit requires a shunt or UVR. Maximum power loss is 25.5 W at rated current — account for that heat in the enclosure thermal calculation.
