The Siemens SENTRON 3VA1112-5ED32-0AF0 is a 3-pole molded case circuit breaker rated for 125 A continuous current at 40 °C ambient, with a TM210 thermal-magnetic overcurrent release. Its interrupting capacity reaches 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — figures that cover most industrial distribution fault levels downstream of a transformer. This is a line-protection design (not motor-protection curve), so it suits feeder circuits, panel mains, and distribution subfeeds where the TM210 release provides short-circuit and overload protection. Built-in trip indicator speeds fault diagnosis — no need to guess which pole tripped. That covers remote status and alarm feedback without an add-on module.
Dimensions are 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). The 3-pole width matches a standard 4-module DIN-rail slot at 18 mm per pole. Depth is shallow enough for 200 mm deep enclosures; verify gland-plate clearance for incoming cables.
