The TM220 thermal-magnetic trip unit provides adjustable overload protection from 14 A to 20 A and a fixed short-circuit pickup of 16 x In. This variant includes a shunt trip (STL) rated 220-250 V DC / 208-277 V AC, two HQ auxiliary switches, and one HQ short-circuit alarm switch, plus a nut keeper kit for secure mounting. The 25 kA Icu at 415 V places this breaker in breaking capacity class N, suitable for downstream distribution in industrial panels where fault currents stay under that threshold. The adjustable Ir (14-20 A) lets you match the thermal trip to the actual continuous load without swapping the breaker body. The fixed Ii at 16 x In (320 A) means magnetic trips are non-adjustable — verify that the inrush of your load (motor starting, transformer energization) does not exceed this pickup to avoid nuisance tripping. ## Integration and deployment The included shunt trip allows remote tripping from a safety circuit or emergency-stop chain.","metaTitle":"Siemens 3VA1120-3EE32-0KM0 Circuit Breaker, 20A, 25kA @ 415V","metaDescription":"Siemens 3VA1120-3EE32-0KM0 IEC 3VA1 frame 160 circuit breaker, 3-pole, 20A, 25kA breaking capacity @ 415V.
