The TM240 release is adjustable for the long-time pickup, so you can dial it down to match the derated conductor ampacity. That's a standard 3-pole MCCB width for a 63 A frame; it'll fit a 200 mm wide DIN-rail section with room for the auxiliary on the side. ## Auxiliary contacts and status feedback The auxiliary tracks the breaker's on/off position; the alarm trips only on a fault event — useful for a remote annunciator or PLC input that distinguishes a manual open from a short-circuit trip. If you need remote tripping or Modbus telemetry, you'd step up to a 3VA2 with the electronic release and communication option.","metaTitle":"Siemens 3VA1163-6EF36-0AF0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens 3VA1163-6EF36-0AF0 SENTRON 3-pole MCCB, 63 A rated, TM240 release, 220 kA at 240 V.
