The Siemens SENTRON 3VA2220-7MP32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 200 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity hits 330 kA at 240 V, 242 kA at 415/440 V, and 187 kA at 500 V, with a sharp drop to 5.2 kA at 690 V. The adjustable trip class (10A, 10/10E, 20/20E, 30) lets you match the thermal-magnetic curve to motor-start or transformer inrush profiles without swapping the breaker.
Key ratings in context
The adjustable trip class (10A, 10/10E, 20/20E, 30) covers fast (10A) through slow (30) overload curves, giving flexibility for motor circuits (Class 10 for standard motors, Class 20 for high-inertia loads).
