That derating curve means you size the breaker for the panel ambient, not the nameplate — at 55 °C you lose 6 A, at 65 °C you lose 18 A. Three poles, line-protection design, no ground-fault module. Short-circuit ratings climb steeply with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That SCCR headroom at the lower voltages lets this breaker sit upstream of a distribution panel without cascading — it clears faults before the main sees them. Insulation voltage rated 800 V, max power loss 42 W. Shunt trip (STL) is built in for remote tripping. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. That depth — 70 mm — is the body only; add the handle throw and wiring space behind the panel. The 3-pole width is standard for this frame size; verify gland-plate clearance if retrofitting into a tight enclosure.","metaTitle":"Siemens 3VA1220-5EF32-0HH0 SENTRON MCCB, 200 A, 3-Pole, 187","metaDescription":"Siemens 3VA1220-5EF32-0HH0 SENTRON molded case circuit breaker, 200 A at 40 °C, 3-pole, 187 kA SCCR at 240 V.
