The Siemens SENTRON 3VA2216-6HL32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 160 A continuous current with an ETU320 electronic overcurrent release. The 242 kA breaking capacity at 240 V gives serious fault-clearing headroom for high-available-fault-current panels — think main breaker or large feeder duty where you need selectivity downstream. At 415 V and 440 V it still interrupts 187 kA, dropping to 121 kA at 500 V and 4.5 kA at 690 V, so the SCCR planning has to track the actual system voltage.
What the ratings mean for fit
The 160 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating headache in a warm enclosure. The ETU320 release is a basic electronic trip unit (no communication, no ground-fault monitoring) suited for standard overload and short-circuit protection on feeders or large branch circuits. The 3-pole frame handles three-phase loads; the IP40 front protection means it lives in a clean panel, not a washdown zone. Dimensions are 105 mm wide × 181 mm high × 86 mm deep — standard MCCB footprint for a 160 A frame.
Panel integration
Mounts on a DIN rail or panel-mount base in the standard SENTRON 3VA2 footprint. The 86 mm depth fits typical distribution boards; leave clearance for cable entry and the ETU320 interface. No undervoltage release or shunt trip fitted on this variant — if you need remote trip, that's a different order code.
