That 250 A holds flat across the first 10 °C of ambient rise — at 55 °C it still carries 241 A, and at 70 °C it's 213 A. For a line-up MCCB in a warm enclosure, that thermal curve buys you headroom without oversizing the frame. Interrupting capacity is 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. ## Integration into the panel Dimensions are 181 mm high, 140 mm wide, 86 mm deep — standard SENTRON 3VA2 4-pole frame. The ETU350 release is field-adjustable for long-time, short-time, instantaneous, and ground-fault (though this unit ships without ground-fault monitoring per).","metaTitle":"Siemens SENTRON 3VA2225-5HN42-0KH0 MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0KH0 molded case circuit breaker, 250 A rated at 40-50 °C, 4-pole, ETU350 release, 187 kA at 240 V.
