The Siemens SENTRON 3VA2116-6HN32-0DA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up.
At 240 V the 242 kA rating is well above typical service-entrance fault levels, giving you selectivity headroom for downstream branch breakers.
The undervoltage release is factory-installed; no separate module to order. Line protection design means it is set up for feeder duty out of the box, not motor protection (no thermal-magnetic adjustment range). If you need adjustable overloads, look at the 3VA2 with electronic trip units.
