What the ratings mean for fit
The SENTRON 3VM1463-4ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 630 A at 40 °C ambient. That rating holds flat through 50 °C — only above 55 °C does it begin to derate, reaching 583 A at 70 °C. The TM210 thermal-magnetic release handles overload and short-circuit protection in one unit, with no undervoltage or shunt trip built in. For a panel builder, this means the breaker is sized for a 630 A feeder or large motor branch circuit in a 480 V or 600 V class distribution, and the 110 mm depth fits standard switchboard mounting. Breaking capacity is specified per voltage: 121 kA at 240 V AC, 76 kA at 415 V and 440 V AC, and 53 kA at 500 V AC. At a typical 480 V industrial service, the interpolated value sits well above 50 kA — enough for most secondary distribution with transformer impedances under 6 %. The 690 V AC rated operating voltage and 800 V rated insulation voltage confirm suitability for 600 V class systems with margin. The front face carries IP40 protection — sufficient for enclosed panel mounting, not for washdown or outdoor exposure. No ground-fault monitoring or communication function is integrated; this is a straight thermal-magnetic breaker for conventional line protection.
Peer comparison — 3VA1112-5EE32-0AA0
The closest functional peer within the SENTRON family is the 3VA1112-5EE32-0AA0. Both are 3-pole MCCBs with thermal-magnetic releases, but the 3VA1112 is a smaller-frame device rated for lower continuous current — typically 100–250 A range versus this part's 630 A. The 3VM1463-4ED32-0AA0 will not drop into a panel cutout designed for the 3VA1112 frame without busbar and mounting modifications; the footprint and lug spacing differ. Select the 3VM1463-4ED32-0AA0 when the load exceeds 300 A and the fault current at the service point demands the higher interrupting capacity.
Environmental and compliance notes
Operating temperature range spans -25 °C to +70 °C, with storage from -40 °C to +80 °C. The 193 W maximum power loss at rated load should be factored into enclosure thermal calculations — a 630 A breaker dissipating nearly 200 W in a sealed cabinet may require forced ventilation above 40 °C ambient.
