What this MCCB covers
The Siemens SENTRON 3VA2116-6HL32-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It's designed for line protection in distribution panels, meaning it handles feeder and main breaker duty where the priority is clearing faults before downstream devices take damage. Breaking capacity is the headline here: 242 kA at 240 VAC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That 242 kA figure at 240 V means it can safely interrupt a fault current up to that level without the arc flashing over or the case rupturing — critical for high-fault installations like transformer secondaries or large motor control centers where available fault current can exceed 100 kA.
Sizing and selectivity
Rated insulation voltage is 800 V, so it's suitable for 480 V and 600 V class systems with margin. The continuous current rating holds flat at 160 A from 40 °C through 70 °C — that's unusual; many MCCBs start derating above 40 °C. If your panel ambient runs hot, this breaker keeps its full ampacity without needing to oversize the frame. Adjustable trip range: 240 A minimum to 1 600 A maximum.
Physical fit and integration
Dimensions are 86 mm deep, 105 mm wide, 181 mm high. That 105 mm width is standard for a 3-pole MCCB in this frame class — it fits the same DIN-rail or panel-mount footprint as other SENTRON 3VA2 breakers. The 86 mm depth means it clears most standard enclosure back-panels without interfering with wiring ducts or bus bars mounted behind it. It ships with one auxiliary switch and one trip alarm switch (HP type) factory-installed, so you don't need to order those separately for remote status indication. No undervoltage release, no ground-fault monitoring, no communication module — this is a straightforward line-protection breaker without add-ons. If you need those, you'd look at the 3VA2 with the 'U' or 'G' option codes.
