What this MCCB carries and where it fits
The Siemens SENTRON 3VA1163-5ED32-0CC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with a TM210 thermal-magnetic release that handles overload and short-circuit protection in one package. The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — those numbers tell you this breaker is built for high-fault panels where a standard MCB would weld shut. It's a line-protection version, meaning it's intended for feeder or main breaker duty rather than motor branch circuit protection, and it carries an undervoltage release (UVR) with two HQ auxiliary switches for status feedback to a PLC or annunciator.
Thermal derating you need to know
The 63 A rating holds flat from 40 °C through 50 °C. Above that it starts to step down: 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. If this breaker sits in a hot enclosure — say next to a drive or inside a non-ventilated panel — the actual continuous current it can carry without nuisance tripping is the derated figure, not the nameplate 63 A. The operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Panel fit and physical integration
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. The width is a standard 3-pole MCCB footprint — it fits the same DIN-rail or mounting-plate hole pattern as other SENTRON 3VA breakers. Front IP40 protection means it's fine inside a closed panel but not for washdown or outdoor exposure without an enclosure. No trip indicator on the front face, so fault status comes from the auxiliary switches or the UVR coil state.
