The Siemens SENTRON 3VA1163-5ED36-0AC0 is a 3-pole molded case circuit breaker rated 63 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V.
Above that it derates: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, 58 A at 70 °C. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and third-party enclosures with a 3-inch wide mounting slot. The 17.3 W maximum power loss means it won't cook adjacent devices in a tightly packed panel, but it's not negligible either — leave some breathing space.
Auxiliary switching and compliance
It's a straight line-protection breaker with basic aux contacts.
