For a panel builder, that means you size your bus and downstream conductors for 200 A and get the full rating in most ventilated enclosures. ## Breaking capacity — what it handles in a fault At 240 V it's rated 187 kA; at 415 V it's 121 kA; at 440 V it's 75.6 kA; at 500 V it's 30 kA; at 690 V it's 17 kA. Those numbers cover most industrial distribution scenarios — a 480 V panel with 65 kA available fault current is well inside the margin. The 690 V rating matters for 600 V class Canadian or mining installations. ## Physical fit and auxiliary options That's a standard 4-pole MCCB footprint — it occupies roughly the same panel space as other 200 A 4-pole frames.","metaTitle":"Siemens 3VA1220-5GF42-0KC0 SENTRON 4-Pole MCCB, 200 A, 187 k","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0KC0 molded case circuit breaker, 4-pole, 200 A rated, 187 kA breaking at 240 VAC.
