The Siemens 3VA1180-3EE42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 25 kA breaking capacity at 415 V (class N). It is configured for line protection with a TM220 thermal-magnetic trip unit, rated at 80 A continuous current (In), with adjustable overload protection (Ir) from 56 A to 80 A and fixed short-circuit protection at 10 times In.
The adjustable Ir band (56–80 A) lets you dial in the overload pickup to match the actual load cable or motor FLA, while the fixed Ii at 10× In means magnetic trip occurs at 800 A — typical for motor-starting inrush or transformer energization. The unprotected N conductor signals this is a 3-pole protected + solid neutral configuration, common in delta or corner-grounded systems where the neutral does not require overcurrent protection.
Deployment Context
The nut keeper kit simplifies captive fastener alignment during assembly — a time-saver on repetitive builds. For a DC Power OEM application, verify the DC voltage rating on the nameplate; the AC 415 V Icu figure does not automatically transfer to DC breaking capacity.
