The Siemens SENTRON 3VA2110-7MN36-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C, designed specifically for motor protection. It carries an interrupting capacity of 330 kA at 240 V and 242 kA at 415 V, dropping to 3.7 kA at 690 V. The breaker includes an undervoltage release and phase failure detection, with a built-in trip indicator and a 2-auxiliary-switch plus 1-trip-alarm-switch configuration. Maximum power dissipation is 12.5 W.
What the ratings mean for fit
The 100 A rating holds across the full 40 °C to 70 °C ambient range — no derating needed for elevated panel temperatures. The 330 kA interrupting capacity at 240 V is the headline figure for fault clearing; at 690 V it drops to 3.7 kA, so verify system voltage against the SCCR curve. The 3-pole design with motor protection curve means it's sized for a three-phase motor load, not a feeder or distribution bus. The undervoltage release (UVR) and phase failure detection are built in, so no external monitoring relay is needed for those functions. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — fits standard SENTRON panel cutouts.
