The Siemens 3VA2116-5KP32-0DA0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 3-pole design carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 800 V rated insulation voltage and 28 W max power loss fit standard panel thermal budgets.
Mounts on a DIN rail or panel plate; dimensions are 105 mm wide, 181 mm high, 86 mm deep — that's 4.13 by 7.13 by 3.39 inches. The 3-pole footprint matches standard SENTRON 3VA2 cutouts. An undervoltage release (UVR) is built in, and the supplied basic switch is order code 3VA21165KP320AA0. No ground-fault monitoring module is included.
Designed for line protection — that means it's the main feeder breaker or large subfeed in a distribution panel, not a motor-circuit protector. The 160 A continuous rating with flat derating to 70 °C makes it a solid choice for high-ambient enclosures or outdoor cabinets where other breakers would need to be oversized.
