The Siemens SENTRON 3VA2216-5HL32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in industrial distribution panels. Its breaking capacity scales with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — meaning it can safely interrupt fault currents up to those levels without cascading upstream, critical for high-fault installations like transformer secondaries or large motor control centers. Rated continuous current holds flat at 160 A across the full ambient range from 40 °C to 70 °C, so no derating is needed in a warm enclosure — a practical advantage over breakers that lose capacity above 40 °C.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or direct-mount panel layouts without re-drilling gland plates. Maximum power dissipation is 19.7 W, so thermal planning inside the enclosure is straightforward; no forced cooling required for a single unit at rated load.
