The Siemens SENTRON 3VA2116-5HN36-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. It's designed for line protection in distribution panels, with a maximum interrupting capacity of 187 kA at 240 V AC and 121 kA at 415/440 V.
Interrupting ratings step down with voltage: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
The supplied basic switch (order code 3VA21165HN360AA0) is the internal switching mechanism — the breaker ships as a complete unit, not a kit.
The breaker carries no trip indicator and no ground-fault monitoring — it's a thermal-magnetic line-protection device, not a GFCI.
