The Siemens SENTRON 3VA2216-5HL32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from -25 °C to 70 °C — no derating needed up to that ceiling. Designed for line protection, it carries a shunt trip release (STL) for remote tripping, making it a fit for distribution panels where an undervoltage release isn't required but a controlled shutdown signal is.
Breaking capacity — what the voltages tell you
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. Those are the interrupting ratings at each voltage level — the fault current it can safely clear without welding contacts or rupturing the case. For a 480 V panel (common in North America), the 121 kA at 440 V is the closest published figure; at 690 V the 4.5 kA rating tells you this breaker is not intended for high-fault 690 V service. The 160 A frame with those interrupting numbers suits it for main or feeder duty in high-available-fault-current industrial switchboards.
Physical fit and panel integration
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is the standard 3-pole MCCB footprint for the 3VA2 frame — it occupies three 35 mm DIN-rail spaces if mounted on a DIN adapter, or bolts directly into the switchboard bus. The 86 mm depth includes the shunt trip mechanism; verify clearance behind the panel door for the STL wiring and any auxiliary switch if added later.
Power loss and thermal management
Maximum power loss is 19.7 W at rated current. That's the heat the breaker dissipates internally — relevant for panel thermal calculations, especially in a sealed enclosure where multiple breakers cluster. At 160 A continuous, 19.7 W per pole is modest; no forced ventilation required in a typical switchboard, but worth checking if the panel is densely packed.
