The 160 A rating holds flat from 40 °C through 50 °C ambient, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. That thermal curve means the breaker can carry its full nameplate in a 50 °C panel without upsizing — a common spec for non-climate-controlled enclosures. Above that, the derating is mild enough that most line-side loads still fit within the same frame. Breaking capacity across voltage bands tells you where this MCCB can be applied without cascading upstream: 187 kA at 240 V suits high-fault industrial panels; 121 kA at 415 V covers standard European distribution; 75.6 kA at 440 V and 17 kA at 690 V handle marine or heavy-industrial feeds. Frame dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole footprint for DIN-rail or screw-mount panel integration. The TM240 thermal-magnetic release is fixed (non-interchangeable in this variant), so the trip curve and rating are locked at 160 A.","metaTitle":"Siemens 3VA1116-5EF32-0AB0 SENTRON MCCB, 160 A, 187 kA at 24","metaDescription":"Siemens 3VA1116-5EF32-0AB0 SENTRON molded case circuit breaker, 160 A rated, 187 kA breaking at 240 V.
