The thermal-magnetic TM220 trip unit gives adjustable overload protection (Ir = 28 A to 40 A) and a fixed short-circuit pickup at 10× In (400 A), so the same breaker can be dialed in for a 32 A motor feeder or a 40 A lighting panel without swapping hardware. ## Deployment context The 4-pole configuration (three phases plus switched neutral) suits a TN-S or TN-C-S system where the neutral must be disconnected for isolation. The N conductor unprotected note means the neutral pole does not carry a trip element; it switches only, so the breaker relies on the phase poles for overcurrent sensing.","metaTitle":"Siemens 3VA1140-5EE42-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1140-5EE42-0AA0-ZD00 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 4-pole, TM220 thermal-magnetic trip, 40A rated.
