It is designed for starter protection in motor branch circuits, meaning the trip curve is shaped to handle high inrush without nuisance trips while still clearing faults quickly. Breaking capacity ranges from 330 kA at 240 V down to 5.2 kA at 690 V — the 330 kA figure at 240 V is among the highest in its class, giving the breaker headroom for high-fault utility feeds or transformer secondaries. At 415/440 V it still holds 242 kA, enough for most industrial panelboards.","metaTitle":"Siemens 3VA2220-7MS32-0CH0 SENTRON MCCB, 600-3000 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2220-7MS32-0CH0 molded case circuit breaker, 3-pole, adjustable 600-3000 A, 200 A at 40-70°C, breaking capacity 330 kA at 240 V.
