What this MCCB does on the line
The Siemens 3VA2116-5HL32-0KA0 is a SENTRON molded case circuit breaker 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 handles line protection in distribution panels, with a shunt trip (STL) auxiliary release for remote or undervoltage-triggered opening. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and still delivers 75.6 kA at 500 V; at 690 V it drops to 3.7 kA, so keep that in mind for higher-voltage taps.
DIN-rail fit and panel integration
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards without re-drilling. The shunt trip release is factory-installed; no field wiring of a separate undervoltage module needed. Max power loss is 25.5 W, so factor that into enclosure thermal calculations if the panel is tightly packed.
