What this MCCB delivers
The Siemens SENTRON 3VM1463-5EE42-0AA0 is a 4-pole molded case circuit breaker rated for 630 A continuous at 40 °C, with a TM220 thermal-magnetic release. The 187 kA breaking capacity at 240 V and 121 kA at 415 V mean it can interrupt high-fault currents without cascading upstream — sized for main or feeder protection in industrial switchboards. TM220 release provides fixed thermal and magnetic trip settings; the li adjustable response value maxes at 5,040 A. No ground-fault monitoring or communication function is built in.
Thermal derating and ambient limits
Current rating holds at 630 A from 40 °C through 50 °C, then derates linearly to 583 A at 70 °C. Operating ambient range is -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. The 193 W maximum power loss should be factored into enclosure ventilation.
Mounting and integration
Dimensions: 248 mm height, 184 mm width, 110 mm depth. The 110 mm depth fits standard distribution panelboards; the 184 mm width for a 4-pole frame is typical for this class. Front IP40 protection suits indoor panel installation — not rated for washdown or outdoor exposure. Rated insulation voltage Ui is 690 V AC; maximum DC operational voltage is 500 V. The neutral conductor is not integrated and cannot be retrofitted — external neutral bar required for 4-wire systems.
