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).
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.
