The Siemens 3VA1163-5EE32-0AE0 is a 3-pole SENTRON molded case circuit breaker (MCCB) built for line protection, with a rated continuous current Iu of 63 A and a TM220 thermal-magnetic overcurrent release. Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that tell you this breaker can handle serious fault currents on distribution transformers or large motor feeders without cascading upstream. That 187 kA at 240 V means this breaker is sized for high-available-fault installations like switchboards close to the utility transformer. At 690 V the 17 kA rating still covers most industrial drives and motor control center feeds. The TM220 release is fixed thermal-magnetic — no electronic adjustment, no communication module, no ground-fault monitoring. It's a straightforward workhorse for panels where you need a hard-wired, no-frills overcurrent protective device.
The 3VA1163-5EE32-0AE0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. It mounts in a standard panel or enclosure footprint — the 76.2 mm width (three 25.4 mm pole spacings) means it fits the same cutouts as other 3-pole SENTRON MCCBs. It carries four auxiliary switches (HQ type) for status feedback to a PLC or annunciator panel. The front face carries an IP40 protection class, so it's fine for indoor switchgear but not for washdown areas. The TM220 release is adjustable for the long-time response (tr max. 1 s), but there's no voltage trigger, undervoltage release, or phase-failure detection built in. If you need those, you add external modules or specify a different version. The latching endurance is rated at 15,000 operations — enough for infrequent switching but not a daily motor-starting duty cycle.
