The Siemens 3VM1180-5EE42-0AA0 is a 4-pole molded case circuit breaker in the 3VM1 family, IEC frame 160, with a 55 kA interrupting capacity at 415 V (breaking capacity class M). It's fitted with a TM220 thermal-magnetic trip unit, rated 80 A continuous, adjustable overload protection from 56 A to 80 A, and fixed short-circuit protection set at 10× In. The 55 kA SCCR at 415 V gives it headroom for high-fault installations upstream of a transformer or in industrial mains.
Integration notes
Packaged dimensions are 150 × 119 × 116 mm. That's a compact footprint for a 160 A frame — fits standard distribution panelboards. The nut keeper kit is pre-fitted on the line-side terminals, so you don't have to fish for washers during busbar connection. Spring-cage terminals on the load side accept copper conductors; strip length and torque values follow the Siemens mounting instructions.
