The Siemens 3VA2216-5HL32-0BL0 is a SENTRON molded case circuit breaker rated for 160 A continuous current, with a flat thermal derating curve from 40 °C to 70 °C — meaning it holds its full 160 A rating across that entire ambient range, no knock-down needed for a warm panel. That's unusual; most MCCBs start derating above 40 °C. Interrupting capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V.
The UVR is built in; verify the coil voltage matches your control circuit before wiring.
