At 690 V it holds 52.5 kA. That kind of headroom matters when the breaker sits downstream of a multi-megawatt turbine transformer — fault currents on a 690 V wind-farm collector ring can spike hard, and this MCCB clears them without cascading upstream. ## Thermal derating — the real-world number Full 200 A holds up to 50 °C ambient. At 55 °C it derates to 192 A, at 60 °C to 188 A, and at 70 °C to 180 A. In a sealed turbine nacelle that hits 60 °C on a summer afternoon, you still have 188 A of continuous capacity — no up-tower swap needed. That covers cold-climate turbine parks and desert solar hybrid sites alike. ## Trip unit and auxiliary releases The ETU350M is an electronic overcurrent release with adjustable settings for motor protection. It includes phase-failure detection, so a lost phase on a conveyor drive or pitch motor trips before the winding cooks. A shunt trip (STL) release is built in — voltage-triggered, so a remote safety PLC or E-stop relay can drop the breaker without a mechanical linkage. If you need remote status feedback, add an auxiliary contact block separately. ## Mechanical endurance and power loss Rated for 20,000 mechanical operations — sufficient for a motor-starting duty cycle on a pump or fan that cycles a few times per shift. Maximum power loss is 75 W, which matters for thermal management inside a compact panel or nacelle cabinet.","metaTitle":"Siemens 3VA2220-7MN32-0JA0 SENTRON MCCB, 200 A, 330 kA at 24","metaDescription":"Siemens 3VA2220-7MN32-0JA0 SENTRON molded case circuit breaker, 200 A rated, 330 kA breaking capacity at 240 VAC.
