Overload protection is adjustable via the TM220 thermal-magnetic trip unit: Ir from 56 A to 80 A, so you dial it to exactly match the cable or load ampacity. Short-circuit magnetic pickup is fixed at 10 x In (800 A), which keeps it selective with downstream branch breakers on motor starts that draw 6-8 x FLA for a few cycles. ## What the protection settings mean for panel coordination The TM220 trip unit gives you thermal adjustment (Ir = 56-80 A) but a fixed magnetic (Ii = 800 A). That fixed short-circuit pickup is typical for line protection — it lets the breaker ride through inrush without nuisance tripping, but it also means you cannot dial down the magnetic threshold to achieve full selectivity with a downstream 20 A branch breaker. If your design requires adjustable short-circuit pickup, you would step up to an electronic trip (ETU) variant in the same 3VM1 frame.","metaTitle":"Siemens 3VM1180-5EE46-0AA2 Circuit Breaker, 80A, 55kA @ 415V","metaDescription":"Siemens 3VM1180-5EE46-0AA2 IEC frame 160 circuit breaker, 80A, 55kA breaking capacity at 415V.
