The Siemens SENTRON 3VA2116-0HL36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in industrial power distribution panels. It carries a massive 440 kA breaking capacity at 415 V AC and 187 kA at 690 V AC — that means it can safely interrupt a fault current up to that level without the arc escaping or the case rupturing, which is critical for high-fault installations like transformer secondaries or large motor control centers. The ETU320 electronic trip unit handles the overcurrent release, giving you adjustable long-time, short-time, and instantaneous protection curves — not just a fixed thermal-magnetic bimetal.
Fit and panel integration
Footprint is 105 mm wide, 181 mm tall, 86 mm deep — standard for a 160 A frame MCCB, so it drops into most existing panel layouts without re-drilling the mounting plate.
If you're freezing a BOM for a new line, this part is a safe bet; no PCN or LTB watch needed today.
