The Siemens SENTRON 3VA2110-7MN32-0JL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full operating temperature range from 40 °C to 70 °C — no derating needed as the panel warms up. The breaking capacity tells you where it can safely interrupt a fault: 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 time band is 4 s minimum to 17 s maximum, and it includes a trip indicator and voltage trigger for remote signaling. This MCCB is designed specifically for motor protection — it includes phase failure detection, so it will trip if one phase drops out, preventing single-phasing damage to the motor. No undervoltage release is fitted, and there is no ground-fault monitoring version on this variant.
If you're swapping out an older frame, check that the 105 mm width matches your existing bus bar spacing and that the 86 mm depth clears the gland plate or door.
Environmental limits and storage
The operating range covers most industrial panel environments, including hot motor control centers.
