The steep drop above 440 V is typical for a frame this size — at 690 V the 17 kA still covers most industrial motor branch circuits, but if your fault current at that voltage exceeds 17 kA you need a higher-rated frame. At 240 V the 220 kA rating is exceptionally high, suitable for large transformer secondaries or high-capacity busway feeds. The 4-pole width (101.6 mm) is standard for a 63 A frame — verify the mounting footprint matches your existing DIN-rail or panel-mount cutout. ## What the TM220 release means for coordination The TM220 designation indicates a thermal-magnetic release with a fixed thermal pickup and adjustable magnetic trip. For selective coordination studies, the fixed thermal curve and magnetic threshold are documented in the Siemens 3VA manual.","metaTitle":"Siemens 3VA1163-6GE42-0AA0 SENTRON MCCB, 63 A, 4-Pole, TM220","metaDescription":"Siemens SENTRON 3VA1163-6GE42-0AA0 molded case circuit breaker, 63 A rated, 4-pole, TM220 release.
