Siemens SENTRON 3VA2110-7MS36-0DH0 — 100 A MCCB, starter protection, 330 kA interrupting
The adjustable overload trip range is 300 A minimum to 1 500 A maximum, so this frame size covers motor FLA from small to mid-range. The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The trip indicator is present. There is no ground-fault monitoring and no communication function — this is a straightforward thermal-magnetic MCCB with a UVR for safety disconnection on loss of control voltage.
The design is starter protection (not a standard feeder breaker), so it includes thermal memory and a higher magnetic pickup curve suited for motor start-up inrush. The factory-fitted undervoltage release means the breaker drops out on control-voltage loss — a common requirement for emergency-stop and safety circuits.
Physical integration
The 86 mm depth keeps it within typical 200 mm enclosure depths. Maximum power loss is 12.5 W at rated current — a useful figure for enclosure thermal calculations when grouping multiple breakers.
