That means in a warm panel — say, 55 °C internal — you lose 9 A of headroom. Plan the load at the actual cabinet temperature, not the nameplate. The breaker dissipates 50.5 W maximum, so factor that into the enclosure thermal budget. Breaking capacity drops with voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. Dimensions: 181 mm height, 140 mm width, 86 mm depth. The supplied basic switch order code is 3VA2225-5HN42-0AA0 — useful for spares planning if the breaker body is swapped but the aux/UV assembly stays.","metaTitle":"Siemens 3VA2225-5HN42-0BC0 SENTRON MCCB, 250A, 4-Pole","metaDescription":"Siemens 3VA2225-5HN42-0BC0 SENTRON molded case circuit breaker, 250 A continuous, 4-pole, breaking capacity 187 kA at 240 V.
