63 A MCCB with 187 kA interrupting capacity at 240 V
The Siemens 3VA1163-5ED32-0AB0 is a SENTRON 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with a TM210 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 — meaning it can safely clear fault currents at those levels without upstream coordination failure. The rated insulation voltage is 800 V, so it's suitable for 480 V and 600 V class panels with headroom.
Thermal derating and ambient limits
The breaker holds full 63 A rating up to 50 °C ambient. Above that it derates linearly: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. Operating range is -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. The IP40 front protection means it's suited for enclosed panel mounting, not open washdown areas.
Auxiliary contacts and release configuration
This variant ships with 2 auxiliary switches (HP type) integrated, but no undervoltage release, no shunt trip (voltage trigger), and no ground fault monitoring. The TM210 release is fixed thermal-magnetic — no adjustable long-time or short-time pickup. There is no communication function or phase failure detection built in. If you need those, you're looking at a different order code in the 3VA family.
Panel fit and dimensions
Dimensions are 70 mm depth, 76.2 mm width, 130 mm height — standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. The 2 auxiliary switches occupy the side slot; verify clearance for wiring access. Latching endurance is rated at 15,000 operations mechanical.
