The 4.5 kA at 690 V is the tail-end capability for 690 V line-ups; if your system runs at 690 V, verify the available fault current stays under that limit. The 160 A rating holds flat from 40 °C through 50 °C, then derates to 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. In a closed panel with ambient rise, that derating curve is the one that governs your actual continuous current — don't size a 160 A breaker for a 160 A continuous load unless you can keep the internal panel ambient at or below 50 °C. Max power loss is 33 W — negligible for thermal budget in a ventilated enclosure, but worth noting if the breaker is packed tightly with other heat sources. ## Auxiliary Switching and Control Wiring","metaTitle":"Siemens 3VA1216-5MH32-0AB0 SENTRON MCCB, 160 A, 3-Pole, Star","metaDescription":"Siemens 3VA1216-5MH32-0AB0 SENTRON molded case circuit breaker, 160 A rated at 40 °C, 3-pole, TM120M release, 187 kA at 240 V.

The 3VA1216-5MH32-0AB0 is a 160 A, 3-pole, TM120M release for starter protection; the 3VA1110-5ED36-0AC0 is a lower-current variant with a different thermal-magnetic curve.
