The Siemens SENTRON 3VA2116-6HL32-0HL0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. The 86 mm depth and 105 mm width fit standard panel-mount cutouts; the 181 mm height leaves room for auxiliary wiring above the line lugs.
Breaking capacity across voltages — selectivity planning
At 240 V the 242 kA rating is the headline figure for high-capacity service-entrance or sub-distribution boards. At 415 V and 440 V the 187 kA rating holds steady, which simplifies coordination in 400 V-class industrial panels. At 690 V the rating falls to 3.7 kA — that's the limit for 690 V bus work, so verify the available fault current if the panel runs at that voltage.
