Siemens SENTRON 3VM1116-3EE32-0AA0 — 160 A MCCB, TM220 Release
The Siemens 3VM1116-3EE32-0AA0 is a 3-pole molded case circuit breaker from the SENTRON line, rated 160 A continuous at 40 °C and designed for line protection. Breaking capacity hits 76 kA at 240 V, 53 kA at 415 V, and 32 kA at 440 V — enough headroom for most industrial secondary-distribution panels.
Thermal Derating and Ambient Range
Full 160 A rating holds from 40 °C through 50 °C. At 55 °C it derates to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A. Operating ambient spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss is 38 W. If the panel runs hot — say a packed enclosure near a furnace line — the 150 A floor at 70 °C still covers most 150 A feeder circuits without upsizing.
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. If your BOM calls for a bare MCCB with no auxiliaries, this is the clean drop-in.
