Rated 200 A at 40 °C, 45 °C, and 50 °C, the 3VA1220-5EF42-0HC0 begins to derate above 50 °C: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C (–). For a panel with a 65 °C internal ambient, the usable current drops to 182 A — factor that into your load schedule. The maximum power loss is 42 W, which contributes to enclosure heating and should be included in the thermal budget for sealed or compact enclosures. ## Breaking Capacity by Voltage Interrupting ratings span the voltage range: 187 kA at 240 VAC, 121 kA at 415 VAC, 75.6 kA at 440 VAC, 30 kA at 500 VAC, and 17 kA at 690 VAC. The 690 V figure confirms suitability for 600 V-class North American systems and 690 V European industrial networks. The 70 mm depth leaves clearance for rear-access wiring in a typical 200 mm deep enclosure. Verify the mounting hole pattern against your existing busbar or lug kit; the 3VA family uses a common bolt-center spacing for 4-pole units.","metaTitle":"Siemens 3VA1220-5EF42-0HC0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5EF42-0HC0 molded case circuit breaker, 200 A rated current, 4-pole, 187 kA breaking capacity at 240 VAC.
