What the ratings mean for fit
The Siemens SENTRON 3VA2116-6HN32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range of 40 °C to 70 °C — no derating needed up to that ceiling. The breaking capacity sits at 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That 242 kA at 240 V means it can safely interrupt a fault current up to that level without cascading upstream — critical for high-fault panels near large transformers or utility feeds. The 3.7 kA at 690 V is the limit for 690 V line-to-line systems; if your service voltage is 690 V, verify the available fault current stays under that figure.
Deployment context
This MCCB mounts in a standard panel or enclosure on a DIN rail or direct-mount plate — the 105 mm width and 86 mm depth fit a typical 600 mm wide panel with room for side-by-side breakers. The shunt trip release (STL) allows remote tripping from a safety circuit or emergency-stop chain, so it integrates into a guarded machine or process line where a fault or E-stop must open the main power feed.
Key electrical ratings
Rated insulation voltage is 800 V, so the breaker is suitable for 480 V and 600 V class systems with margin. Power loss at rated current is 25.5 W maximum — factor that into enclosure thermal calculations if the panel is densely packed. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The shunt trip release is a voltage-trigger type, not undervoltage; it requires a control voltage to fire, so plan for a separate control circuit.
