The Siemens 3VA1116-3EE32-0LC0 is a 3-pole IEC frame 160 molded-case circuit breaker with a 25 kA interrupting capacity at 415 V (breaking capacity class N). It carries a TM220 thermal-magnetic release — fixed thermal and magnetic — with an adjustable overload protection band from 112 A to 160 A and a fixed short-circuit pickup of 10 times the rated current (Ii = 10 x In). The accessory also provisions up to 2 auxiliary switch changeover contacts for status feedback.
The TM220 release is factory-set but the Ir adjustment dial (112–160 A) lets you match the breaker to the actual load without swapping the trip unit — useful when the same frame size serves multiple motor or feeder circuits on a panel.
