The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir=140 A to 200 A) and fixed short-circuit protection (Ii=5 to 10 × In), so you set the Ir to match the conductor or load ampacity, not the frame size. ## Deployment context The nut keeper kit included is specific to DC Power OEM builds in China — it secures the breaker against vibration in transport or high-vibration line-side applications. The 3-pole form factor handles three-phase loads; the 200 A frame and 55 kA SCCR suit it for main or feeder protection in industrial switchboards where fault currents run high.","metaTitle":"Siemens 3VA1220-5EF32-0AA0-ZD00 Circuit Breaker, 200A, 55kA","metaDescription":"Siemens 3VA1220-5EF32-0AA0-ZD00 IEC frame 250 circuit breaker, 3-pole, 200A, 55kA breaking capacity @ 415V.
