Two HQ auxiliary switches are built in, giving status feedback for the open/closed position without needing an external contact block. ## Current derating and thermal performance Above that, current must be derated: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. For a panel running warm — say 55 °C internal ambient — the effective continuous current drops about 4 %, which matters when sizing for a near-full bus. The breaker accepts plug-in or fixed connections depending on the base adapter; verify the panel's busbar pitch against the 76.2 mm width before committing the cutout.","metaTitle":"Siemens 3VA1116-6EF32-0KC0 SENTRON MCCB, 160 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1116-6EF32-0KC0 molded case circuit breaker, 160 A, 3-pole, 220 kA at 240 V.
