This breaker carries a 220 kA interrupting rating at 240 VAC, 154 kA at 415 VAC, 36 kA at 440 VAC, and 17 kA at 690 VAC. The steep drop between 415 V and 440 V reflects the transition from the IEC 60898-1 test voltage to the higher 440 V level where arc extinction becomes harder. For a 400 V distribution board (the most common industrial voltage in Europe and Asia), the 154 kA figure gives substantial headroom above typical transformer-fed fault currents of 25–50 kA. At 690 V, the 17 kA rating still covers most low-voltage motor control centre (MCC) applications. The 220 kA at 240 V is relevant for North American 120/208 V or 277/480 V systems where the line-to-neutral fault can be extreme near a large step-down transformer. It is a fixed-mount (non-withdrawable) MCCB designed for screw-mounting onto a backplate or mounting plate inside a distribution panel. No auxiliary contacts or shunt trip are included as-delivered, but the design accepts the 3VA9688-0BL33 auxiliary trip block if remote tripping is needed.","metaTitle":"Siemens 3VA1220-6EF42-0KA0 SENTRON MCCB, 200 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0KA0 molded case circuit breaker, 200 A continuous, 4-pole, 220 kA breaking capacity at 240 VAC.
