Siemens SENTRON 3VA2216-7HN32-0JH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity sits at 330 kA at 240 V AC, stepping down to 242 kA at 415 V and 440 V, then 187 kA at 500 V. At 690 V it still clears 4.5 kA.
Power loss maxes at 19.7 W — manageable for panel thermal budgeting. The trip indicator and voltage trigger are standard on this variant, meaning you get visual trip flag and remote voltage sensing without extra hardware. No undervoltage release on this order code, so if you need UVR protection, that's a separate accessory.
