The Siemens SENTRON 3VA2116-6HL32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 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 — so it handles high-fault utility feeds at the lower voltages and still clears a 690 V fault, though the margin tightens there.
Maximum power loss is 28 W, so ventilation in a sealed enclosure is advisable if multiple breakers are ganged — that heat adds up.
The 160 A continuous rating at 40-70 °C means this breaker carries a full 160 A load even in a hot panel near the top of its ambient range. At 415 V the 187 kA still covers most industrial service entrances.
