What this 3VA1 frame breaker delivers
The Siemens 3VA1116-5ED32-0LC0 is a 3-pole IEC frame 160 molded case circuit breaker rated for 160 A continuous, with a thermal-magnetic TM210 trip unit providing fixed overload protection at Ir=160 A and fixed short-circuit protection at Ii=10 x In (1600 A). Its breaking capacity class M delivers Icu=55 kA at 415 V AC, which means it can safely interrupt fault currents up to that level on a 415 V line without upstream cascading — a spec that governs selectivity coordination in a distribution panel. The unit includes a factory-fitted nut keeper kit and a universal release accessory for 24 V DC control, plus up to 2 auxiliary switch changeover contacts for status feedback to a PLC or indication circuit.
Integration notes for the panel builder
Mounts on a DIN rail or directly to a backplate via the frame's integral lugs. The 160 A frame occupies standard panel space for a 3-pole IEC MCCB; verify fill factor and thermal derating when grouping multiple breakers in a sealed enclosure. The 24 V DC universal release allows remote tripping from a safety PLC or emergency-stop circuit — wire polarity matters; per the datasheet, verify free-wheel diode orientation if driving an inductive load on the same coil circuit.
