The Siemens SENTRON 3VA1116-4ED26-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated 160 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release providing LI (long-time and instantaneous) protection. Its interrupting capacity reaches 121 kA at 240 V AC and 75.6 kA at 415 V AC — numbers that matter when you're coordinating selectivity downstream of a transformer or tying into a high-fault bus.
Deployment context
This MCCB mounts on a DIN rail or panel-mount base in a distribution board or motor control center. The IP40 front protection means it's suited for indoor, dry enclosures — not washdown or outdoor exposure without an additional enclosure. The 70 mm depth and 50.8 mm width fit standard SENTRON 3VA panel footprints, so it swaps into existing 2-pole slots without re-drilling.
