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. 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.

Key electrical ratings
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.
