The 690 V figure (11.9 kA) is relevant for 690 V industrial drives or mining gear; not every 160 A frame carries that rating. ## Thermal derating — the real-world current you can count on At 55 °C it drops to 155.6 A, at 60 °C to 151.2 A, at 65 °C to 146.8 A, and at 70 °C to 142.4 A. For a panel that runs warm — say 55 °C ambient inside the enclosure — you lose about 4.4 A off the nameplate. That matters when sizing for a continuous load near the limit; the breaker won't nuisance-trip, but the margin shrinks. IP40 on the front (protected against tools and small wires), rated for operation from -25 °C to 70 °C and storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA1216-4EF32-0AH0 SENTRON MCCB, 160 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1216-4EF32-0AH0 molded case circuit breaker, 160 A rated continuous current, 3-pole, line protection version.
