Rated 250 A up to 50 °C, then derates linearly: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. If your panel ambient runs 60 °C — say, a crowded enclosure with drives — the breaker still delivers 237 A continuous without nuisance tripping. ## Breaking Capacity Across Voltages Breaking capacity drops as system voltage rises: 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. For a 480 V distribution panel, the 75.6 kA figure gives you headroom above typical 65 kA SCCR requirements — useful for utility-feed applications where fault current runs high. ## Environmental and Mechanical Specs ## Auxiliary Switching and Release Configuration No undervoltage release fitted, no ground-fault monitoring module. The shunt trip lets a safety PLC or E-stop circuit kill the breaker directly — wire it to a 24 VDC signal from your safety relay.","metaTitle":"Siemens 3VA1225-5EF32-0HH0 SENTRON MCCB, 250A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1225-5EF32-0HH0 molded case circuit breaker, 250A rated at 40°C, 3-pole, 187kA breaking capacity at 240V.
