The SENTRON 3VA1463-7EF32-0AA0 is a 3-pole molded case circuit breaker rated for 630 A continuous current, built for line-protection duty in distribution panels and switchboards. Its TM240 thermal-magnetic release handles overload and short-circuit coordination without an external trip unit.
Interrupting capacity across voltages
This breaker delivers 440 kA at 240 V, 242 kA at 415 V and 440 V, 154 kA at 500 V, and 17 kA at 690 V. That spread means it can be specified for high-fault panels at low voltage and still hold coordination at higher system voltages — the 242 kA at 415 V covers most industrial 400 V distribution without needing an upstream current-limiting fuse.
Thermal derating and operating range
Rated 630 A from 40 °C through 50 °C ambient. Above that, the continuous current drops: 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. If the panel runs hot — say a non-ventilated enclosure near a furnace line — size the load side for the derated figure, not the nameplate. Operating ambient spans -25 °C to 70 °C; storage from -40 °C to 80 °C.
Dimensions and panel fit
Footprint is 138 mm wide by 248 mm tall, with a depth of 110 mm. That 138 mm width is the standard 3-pole MCCB form factor for this current class — it fits existing SENTRON mounting plates and busbar systems without adapter brackets. Power loss at full load is 192.9 W, so account for that heat in the enclosure sizing.
