The TM240 release is fixed-trip thermal with a magnetic pickup; the adjustable time delay tr maxes at 1 s. The two HQ auxiliary switches (form C) are built in, so you get status feedback without an add-on block. Depth is 70 mm, width 76.2 mm, height 130 mm; it fits the standard SENTRON mounting footprint, so swapping into an existing 3VA panel cutout is straightforward. ## Thermal derating — read the real current at your panel ambient At 55 °C it derates to 153.6 A, at 60 °C to 150.4 A, at 65 °C to 147.2 A, and at 70 °C to 144 A. That matters for a feeder sized at 160 A; you'd want to verify the connected load doesn't exceed the derated value. The storage limit is wider because the breaker isn't carrying current — that's the handling envelope, not the running one.","metaTitle":"Siemens 3VA1116-3EF36-0AC0 MCCB, 160 A, 75.6 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1116-3EF36-0AC0 molded case circuit breaker, 160 A rated current, 75.6 kA breaking capacity at 240 V. 3-pole, TM240 release, 2 HQ aux switches.
