Breaking capacity is where this unit earns its keep in a distribution panel: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V. The 415 V and 440 V numbers are identical, so coordination studies at either voltage use the same let-through curve. That means the thermal pickup and magnetic instantaneous are factory-set for the 160 A frame. If the application needs adjustable long-time or short-time pickup, you'd step up to an electronic release in the same 3VA family. For a fixed-load feeder or a non-critical motor branch, the TM240 keeps the BOM simple and the panel build predictable. Rated 160 A continuous at 40 °C, but the 3VA1332-5FF42-0AA0 holds that same 320 A frame rating (the internal thermal capacity of the breaker body) all the way up to 50 °C. At 55 °C it derates to 313 A, at 60 °C to 306 A, at 65 °C to 299 A, and at 70 °C to 292 A. For a 160 A breaker that's generous headroom — the TM240 release itself is the limiting element, not the frame. In a sealed panel hitting 55 °C you still have full 160 A capability. Dimensions: 248 mm high, 184 mm wide, 110 mm deep. Standard 4-pole MCCB footprint. If the BOM calls for remote trip or status feedback, you need the accessory slot version or a different 3VA variant. The upside: no auxiliary wiring to land, no coil supervision to troubleshoot.","metaTitle":"Siemens 3VA1332-5FF42-0AA0 SENTRON MCCB, 160 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1332-5FF42-0AA0 molded case circuit breaker, 160 A rated, 4-pole, TM240 release.
